This adds error handling to the remaining dma_map_single() calls, so that behavior is well defined if/when we run out of DMA memory. Fixes: 92744989533c ("net: add Xilinx ll_temac device driver") Signed-off-by: Esben Haabendal <esben@geanix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-02-24net: ll_temac: Fix race condition causing TX hangEsben Haabendal
It is possible that the interrupt handler fires and frees up space in the TX ring in between checking for sufficient TX ring space and stopping the TX queue in temac_start_xmit. If this happens, the queue wake from the interrupt handler will occur before the queue is stopped, causing a lost wakeup and the adapter's transmit hanging. To avoid this, after stopping the queue, check again whether there is sufficient space in the TX ring. If so, wake up the queue again. This is a port of the similar fix in axienet driver, commit 7de44285c1f6 ("net: axienet: Fix race condition causing TX hang").

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fix LCD backlight issue for droid4 There was a bit of an integration glitch with the LED backlight series. The LED related parts got merged into v5.6-rc1, but the actual backlight driver got left out. This caused an issue on at least droid4 where the LCD backlight can not yet be enabled automatically. And the LCD backlight can no longer be enabled manually either via sysfs. The integration glitch happened because some pending comments from me. There was some confusion on which device tree property we should use for the default brightness property. After discussing how to fix this on the mailing lists, we came to the conclusion that it's best to fix this issue properly by adding the missing driver. The other solutions would mean backpedaling and try to come up with some temporary solution that really does not solve the issue for users. The patch for led_bl.c has been around for quite a while and tested by many users and was assumed to be merged as part of the LED backlight series. For the brightness property to use, we ended up using the more common "default-brightness-level" rather than "default-brightness" used by some backlight drivers. * tag 'omap-for-v5.6/droid4-lcd-fix-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: droid4: Configure LED backlight for lm3532 backlight: add led-backlight driver Link: https://lore.kernel.org/r/pull-1582303901-96693@atomide.com Signed-off-by: Olof Johansson <olof@lixom.net>

2020-02-24scsi: zfcp: fix wrong data and display format of SFP+ temperatureBenjamin Block
When implementing support for retrieval of local diagnostic data from the FCP channel, the wrong data format was assumed for the temperature of the local SFP+ connector. The Fibre Channel Link Services (FC-LS-3) specification is not clear on the format of the stored integer, and only after consulting the SNIA specification SFF-8472 did we realize it is stored as two's complement. Thus, the used data and display format is wrong, and highly misleading for users when the temperature should drop below 0°C (however unlikely that may be). To fix this, change the data format in `struct fsf_qtcb_bottom_port` from unsigned to signed, and change the printf format string used to generate `zfcp_sysfs_adapter_diag_sfp_temperature_show()` from `%hu` to `%hd`.

2020-02-24scsi: sd_sbc: Fix sd_zbc_report_zones()Damien Le Moal
The block layer generic blk_revalidate_disk_zones() checks the validity of zone descriptors reported by a disk using the blk_revalidate_zone_cb() callback function executed for each zone descriptor. If a ZBC disk reports invalid zone descriptors, blk_revalidate_disk_zones() returns an error and sd_zbc_read_zones() changes the disk capacity to 0, which in turn results in the gendisk structure capacity to be set to 0. This all works well for the first revalidate pass on a disk and the block layer detects the capactiy change. On the second revalidate pass, blk_revalidate_disk_zones() is called again and sd_zbc_report_zones() executed to check the zones a second time. However, for this second pass, the gendisk capacity is now 0, which results in sd_zbc_report_zones() to do nothing and to report success and no zones. blk_revalidate_disk_zones() in turn returns success and sets the disk queue chunk_sectors limit with zero as no zones were checked, causing a oops to trigger on the BUG_ON(!is_power_of_2(chunk_sectors)) in blk_queue_chunk_sectors(). Fix this by using the sdkp capacity field rather than the gendisk capacity for the report zones loop in sd_zbc_report_zones(). Also add a check to return immediately an error if the sdkp capacity is 0. With this fix, invalid/buggy ZBC disk scan does not trigger a oops and are exposed with a 0 capacity. This change also preserve the chance for the disk to be correctly revalidated on the second revalidate pass as the scsi disk structure capacity field is always set to the disk reported value when sd_zbc_report_zones() is called.

2020-02-24dmaengine: imx-sdma: fix context cacheMartin Fuzzey
There is a DMA problem with the serial ports on i.MX6. When the following sequence is performed: 1) Open a port 2) Write some data 3) Close the port 4) Open a *different* port 5) Write some data 6) Close the port The second write sends nothing and the second close hangs. If the first close() is omitted it works. Adding logs to the the UART driver shows that the DMA is being setup but the callback is never invoked for the second write. This used to work in 4.19. Git bisect leads to: ad0d92d: "dmaengine: imx-sdma: refine to load context only once" This commit adds a "context_loaded" flag used to avoid unnecessary context setups. However the flag is only reset in sdma_channel_terminate_work(), which is only invoked in a worker triggered by sdma_terminate_all() IF there is an active descriptor. So, if no active descriptor remains when the channel is terminated, the flag is not reset and, when the channel is later reused the old context is used. Fix the problem by always resetting the flag in sdma_free_chan_resources().

2020-02-24media: hantro: Write quantization table registers in increasing addresses orderAndrzej Pietrasiewicz
Luma and chroma qtables need to be written into two 16-register blocks, each table consisting of 64 bytes total. The blocks are contiguous and start at offset 0 for luma and at offset 0x40 for chroma. The seemingly innocent optimization of writing the two blocks using one loop causes side effects which result in improper values of quantization tables being used by the hardware during encoding. Visually this results in macroblocking artifacts around contrasting edges in encoded images. The artifacts look like horizontally flipped shadows of the said edges. Changing the write operations to non-relaxed variant doesn't help. This patch removes this premature optimization and after this change the macroblocking artifacts around contrasting edges are gone.

2020-02-24media: hantro: Write the quantization tables in proper orderAndrzej Pietrasiewicz
The quantization tables as defined in the file (luma_q_table, chroma_q_table) are in fact in linear order. The JPEG file header, which is not generated by the hardware, but must be programatically created with the CPU, expects the table in zigzag order. On the other hand, the hardware doesn't expect neither linear, nor zigzag order. Instead it expects the quantization tables in vertical groups of four quantization parameters, and the groups are organized in blocks of two vertically adjacent groups. On top of that the blocks must be provided to the hardware in this order: leftmost top block, leftmost bottom block, second leftmost top block, second leftmost bottom block and so on. So, if this is the quantization table in linear order: 0x10, 0x0b, 0x0a, 0x10, 0x18, 0x28, 0x33, 0x3d, 0x0c, 0x0c, 0x0e, 0x13, 0x1a, 0x3a, 0x3c, 0x37, 0x0e, 0x0d, 0x10, 0x18, 0x28, 0x39, 0x45, 0x38, 0x0e, 0x11, 0x16, 0x1d, 0x33, 0x57, 0x50, 0x3e, 0x12, 0x16, 0x25, 0x38, 0x44, 0x6d, 0x67, 0x4d, 0x18, 0x23, 0x37, 0x40, 0x51, 0x68, 0x71, 0x5c, 0x31, 0x40, 0x4e, 0x57, 0x67, 0x79, 0x78, 0x65, 0x48, 0x5c, 0x5f, 0x62, 0x70, 0x64, 0x67, 0x63 then the hardware expects this in its consecutive registers: 0x100c0e0e, 0x0b0c0d11, 0x12183148, 0x1623405c, 0x0a0e1016, 0x1013181d, 0x25374e5f, 0x38405762, and so on. Consequently, the same area of memory cannot be used both for dumping it into the JPEG file header and writing its contents to the hardware registers. Instead, a separate pair of arrays is added for properly reordered quantization tables, to be read with get_unaligned_be32() and linearly written to the registers. The "ctx" parameter is not needed any more for hantro_jpeg_get_qtable().

Since (luma/chroma)_qtable is an array of unsigned char, indexing it returns consecutive byte locations, but we are supposed to read the arrays in four-byte words. Consequently, we should be pointing get_unaligned_be32() at consecutive word locations instead.

2020-02-24media: vimc: streamer: if kthread_stop fails, ignore the errorDafna Hirschfeld
Ignore errors returned from kthread_stop since the vimc subdevices should still be notified that streaming stopped so they can release the memory for the streaming, and also kthread should be set to NULL. kthread_stop can return -EINTR in case the thread did not yet run. This can happen if userspace calls streamon and streamoff right after.

2020-02-24media: staging: media: rkisp1: make links immutable by defaultHelen Koike
The only places which make sese to allow users to enable or disable links are: * between sensors and isp: So users can select which sensor should be used while streaming * between isp and the resizers: | v here rkisp1_isp:2 -> rkisp1_resizer_mainpath -> rkisp1_mainpath (capture) \-> rkisp1_resizer_selfpath -> rkisp1_selfpath (capture) ^ here | So users can disable one of the capture paths when unused, to avoid worring about matching formats. Make the following links immutable to simplify userspace: rkisp1_resizer_mainpath -> rkisp1_mainpath rkisp1_resizer_selfpath -> rkisp1_selfpath rkisp1_params -> rkisp1_isp rkisp1_isp -> rkisp1_stats Signed-off-by: Helen Koike <helen.koike@collabora.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

We currently have the following devnode types: enum vfl_devnode_type { VFL_TYPE_GRABBER = 0, VFL_TYPE_VBI, VFL_TYPE_RADIO, VFL_TYPE_SUBDEV, VFL_TYPE_SDR, VFL_TYPE_TOUCH, VFL_TYPE_MAX /* Shall be the last one */ }; They all make sense, except for the first: GRABBER really refers to /dev/videoX devices, which can be capture, output or m2m, so 'grabber' doesn't even refer to their function anymore. Let's call a spade a spade and rename this to VFL_TYPE_VIDEO.
