2015-04-09ASoC: Don't try to register debugfs entries if the parent does not existLars-Peter Clausen
If the registration of a debugfs directory fails this is treated as a non-fatal error in ASoC and operation continues as normal. This means we need to be careful and check if the parent debugfs directory exists if we try to register a debugfs file or sub-directory. Otherwise we might end up passing NULL for the parent and the file or directory will be registered in the top-level debugfs directory.

2015-04-09ocfs2: _really_ sync the right rangeAl Viro
"ocfs2 syncs the wrong range" had been broken; prior to it the code was doing the wrong thing in case of O_APPEND, all right, but _after_ it we were syncing the wrong range in 100% cases. *ppos, aka iocb->ki_pos is incremented prior to that point, so we are always doing sync on the area _after_ the one we'd written to.

2015-04-09ASoC: Make soc_dpcm_debugfs_add() non-fatalLars-Peter Clausen

2015-04-09ASoC: rt286: Restore default in probeBard Liao
RT286 can't do register reset. If the hardware power is still existing in power off, rt286 will keep the register settings. So, we need to restore the default register value in probe to make sure the cache value is the same as the real register value.

2015-04-09ALSA: hda/realtek - Fix the regression by widget power-savingTakashi Iwai
While enabling the widget power-saving for ALC269 & co, the important setup was forgotten -- stream_pm ops. Without this setup, the paths for PCM won't be powered up at all. Also, the power_filter callbacks used in ALC269 & co need to chain to the default snd_hda_gen_path_power_filter().

2015-04-09ASoC: Intel: do cast earlier in sst_cdev_tstamp()Dan Carpenter
My static checker complains about these because it looks like the multiply can overflow and then we cast to a larger data type.

2015-04-09mfd: sec: Fix RTC alarm interrupt number on S2MPS11Krzysztof Kozlowski
The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of RTC alarms 0 and 1 were inversed between these two devices. So when rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to S2MPS11_IRQ_RTCA1, not RTCA0.

2015-04-09ALSA: hda/generic - Don't override power_filter when power_save_node is setTakashi Iwai
Currently the generic parser sets codec->power_filter when power_save_node flag is set.

2015-04-09mmc: sdhci-esdhc-imx: Call mmc_of_parse()Fabio Estevam
Currently it is not possible to use 'mmc-pwrseq-simple' property with this driver because mmc_of_parse() is never called. mmc_of_parse() calls mmc_pwrseq_alloc() that manages MMC power sequence and allows passing GPIOs in the devicetree to properly power/reset the Wifi chipset. When using mmc_of_parse() we no longer need to have custom code to request card-detect and write-protect pins, as this can now be handled by the mmc core. Tested on a imx6sl-warp board where BT/Wifi is functional and also on a imx6q-sabresd. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

Although the cmd11 interrupt should come within 2ms, that's a very short time. Let's increase the timeout to be really sure that we don't get an accidnetal timeout. One case in particular this is useful is if you've got a serial console and printk in just the right places. Under that scenario I've seen delays of up to 130ms before the interrupt fired. CMD11 is only sent during card insertion, so this extra timeout shouldn't be terrible.

2015-04-09mmc: dw_mmc: fix fifo ordering in big endianBen Dooks
The dw_mmc driver changes to make the IO accesors endian agnostic did not take into account the fifo accesses do not need to be swapped. To fix this add a mmci_fifo_read/write wrapper to allow these to be passed through the IO without being swapped. Since these are now specific functions, it would be easier just to store the pointer to the fifo registers in the host block instead of the offset to them. So change the host->data_offset to host->fifo_reg (which also means we catch all the places this is read or written).

2015-04-09mmc: dw_mmc: change idmac descriptor files to __le32Ben Dooks
The dw_mmc driver does not take into account the processor may be in big endian when writing the descriptors. Change the descriptors for the 32bit IDMA to use __le32 and ensure they are suitably swapped before writing. Note, this has not been tested as the socfpga driver does not try to use idma.

2015-04-09mmc: dw_mmc: make IO accessors endian agnosticBen Dooks
The dw_mmc driver does not use endian agnostic IO accessors, so fix the use of __raw reads and writes to be the relaxed versions. This fixes the dw_mmc driver initialisation on Altera socfpga in big endian.

2015-04-09ALSA: hda - Always allow access for POWER_STATE verbs via regmapTakashi Iwai
The hdac regmap code checks whether the codec is powered on while accessing, but there must be an exception -- the verbs to control the power state. Currently HD-audio driver doesn't access them via regmap, so this patch doesn't fix any current behavior, but it's just for future. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-09locking/mutex: Further simplify mutex_spin_on_owner()Jason Low
Similar to what Linus suggested for rwsem_spin_on_owner(), in mutex_spin_on_owner() instead of having while (true) and breaking out of the spin loop on lock->owner != owner, we can have the loop directly check for while (lock->owner == owner) to improve the readability of the code. It also shrinks the code a bit: text data bss dec hex filename 3721 0 0 3721 e89 mutex.o.before 3705 0 0 3705 e79 mutex.o.after Signed-off-by: Jason Low <jason.low2@hp.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Aswin Chandramouleeswaran <aswin@hp.com> Cc: Davidlohr Bueso <dave@stgolabs.net> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Paul E.

2015-04-09Bluetooth: Read LE remote features during connection establishmentMarcel Holtmann
When establishing a Bluetooth LE connection, read the remote used features mask to determine which features are supported. This was not really needed with Bluetooth 4.0, but since Bluetooth 4.1 and also 4.2 have introduced new optional features, this becomes more important. This works the same as with BR/EDR where the connection enters the BT_CONFIG stage and hci_connect_cfm call is delayed until the remote features have been retrieved. Only after successfully receiving the remote features, the connection enters the BT_CONNECTED state.

2015-04-09switch kernel_sendmsg() and kernel_recvmsg() to iov_iter_kvec()Al Viro
For kernel_sendmsg() that eliminates the need to play with setfs(); for kernel_recvmsg() it does *not* - a couple of callers are using it with non-NULL ->msg_control, which would be treated as userland address on recvmsg side of things. In all cases we are really setting a kvec-backed iov_iter, though. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
