2019-01-15ASoC: core: Don't defer probe on optional, NULL componentsMatthias Reichl
cpu and platform are optional components in DAI links. For example codec-codec links usually have no platform set. Call snd_soc_find_component only if the name or of_node of a cpu or platform is set. Otherwise it will return NULL and soc_init_dai_link bails out immediately with -EPROBE_DEFER, meaning registering a card with NULL cpu or platform in DAI links can never succeed.

2019-01-15ASoC: core: Make snd_soc_find_component() more robustMark Brown
There are some use cases where you're checking for a lot of things on a card and it makes sense that you might end up trying to call snd_soc_find_component() without either a name or an of_node. Currently in that case we try to dereference the name and crash but it's more useful to allow the caller to just treat that as a case where we don't find anything, that error handling will already exist. Inspired by a patch from Ajit Pandey fixing some callers.

2019-01-14ASoC: soc-core: fix init platform memory handlingCurtis Malainey
snd_soc_init_platform initializes pointers to snd_soc_dai_link which is statically allocated and it does this by devm_kzalloc. In the event of an EPROBE_DEFER the memory will be freed and the pointers are left dangling. snd_soc_init_platform sees the dangling pointers and assumes they are pointing to initialized memory and does not reallocate them on the second probe attempt which results in a use after free bug since devm has freed the memory from the first probe attempt. Since the intention for snd_soc_dai_link->platform is that it can be set statically by the machine driver we need to respect the pointer in the event we did not set it but still catch dangling pointers. The solution is to add a flag to track whether the pointer was dynamically allocated or not. Signed-off-by: Curtis Malainey <cujomalainey@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2019-01-07ASoC: tlv320aic32x4: Kernel OOPS while entering DAPM standby modeb-ak
During the bootup of the kernel, the DAPM bias level is in the OFF state. As soon as the DAPM framework kicks in it pushes the codec into STANDBY state. The probe function doesn't prepare the clock, and STANDBY state does a clk_disable_unprepare() without checking the previous state. This leads to an OOPS. Not transitioning from an OFF state to the STANDBY state fixes the problem. Signed-off-by: b-ak <anur.bhargav@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org

2019-01-03ALSA: compress: prevent potential divide by zero bugsDan Carpenter
The problem is seen in the q6asm_dai_compr_set_params() function: ret = q6asm_map_memory_regions(dir, prtd->audio_client, prtd->phys, (prtd->pcm_size / prtd->periods), ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ prtd->periods); In this code prtd->pcm_size is the buffer_size and prtd->periods comes from params->buffer.fragments. If we allow the number of fragments to be zero then it results in a divide by zero bug. One possible fix would be to use prtd->pcm_count directly instead of using the division to re-calculate it. But I decided that it doesn't really make sense to allow zero fragments. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Create new directory to contain all Texas Instruments specific DAI, platform and machine drivers instead of scattering them under davinci and omap directories. There is already inter dependency between the two directories becasue of McASP (on dra7x it is serviced by sDMA, not EDMA). With the upcoming AM654 we will need to introduce new platform driver for UDMA and it does not fit under davinci, nor under omap. With the move I have restructured the Kconfig to be more usable in the era of simple-sound-card: CPU DAIs can be selected individually and they will select the platform driver they can be served with. To avoid breakage, I have moved over deprecated Kconfig options so defconfig builds will work without regression.

2018-12-14scripts/spdxcheck.py: always open files in binary modeThierry Reding
The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).

2018-12-14fs/iomap.c: get/put the page in iomap_page_create/release()Piotr Jaroszynski
migrate_page_move_mapping() expects pages with private data set to have a page_count elevated by 1. This is what used to happen for xfs through the buffer_heads code before the switch to iomap in commit 82cb14175e7d ("xfs: add support for sub-pagesize writeback without buffer_heads"). Not having the count elevated causes move_pages() to fail on memory mapped files coming from xfs. Make iomap compatible with the migrate_page_move_mapping() assumption by elevating the page count as part of iomap_page_create() and lowering it in iomap_page_release(). It causes the move_pages() syscall to misbehave on memory mapped files from xfs. It does not not move any pages, which I suppose is "just" a perf issue, but it also ends up returning a positive number which is out of spec for the syscall. Talking to Michal Hocko, it sounds like returning positive numbers might be a necessary update to move_pages() anyway though (https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz). I only hit this in tests that verify that move_pages() actually moved the pages. The test also got confused by the positive return from move_pages() (it got treated as a success as positive numbers were not expected and not handled) making it a bit harder to track down what's going on.

This define is used by arm64 to calculate the size of the vmemmap region. It is defined as the log2 of the upper bound on the size of a struct page. We move it into mm_types.h so it can be defined properly instead of set and checked with a build bug. This also allows us to use the same define for riscv.

2018-12-14alpha: fix hang caused by the bootmem removalMike Rapoport
The conversion of alpha to memblock as the early memory manager caused boot to hang as described at [1]. The issue is caused because for CONFIG_DISCTONTIGMEM=y case, memblock_add() is called using memory start PFN that had been rounded down to the nearest 8Mb and it caused memblock to see more memory that is actually present in the system. Besides, memblock allocates memory from high addresses while bootmem was using low memory, which broke the assumption that early allocations are always accessible by the hardware. This patch ensures that memblock_add() is using the correct PFN for the memory start and forces memblock to use bottom-up allocations.

A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use tracehook_report_syscall_entry() properly. We'll rework the code in next to avoid the empty if body. Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver. The driver was finally able to be tested on the other hypervisor which exposed several bugs. The fixes are all fairly minimal at least. Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI capable PHB, only seen on older hardware (MPC8378). Fix our legacy serial code to look for "stdout-path" since the device trees were updated to use that instead of "linux,stdout-path". A change to the COFF zImage code to fix booting old powermacs.
