It seems that the resolution of vc04 callback is in 10 msec; i.e. the minimal period size is also 10 msec. This patch adds the corresponding hw constraint. Signed-off-by:

The chip->audio_mutex is used basically for protecting the opened stream assignment, and the prepare callback is irrelevant with it. Signed-off-by:

These debug messages worsen the code readability a lot while they give little debuggability (which we already have via tracing, in anyway). Let's clean them up. This allows us to reduce the snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the snd_pcm_lib_ioctl callback (like most other drivers do), too. Signed-off-by:

The hw_queue_size of PCM indirect helper doesn't need to be set up if you use the whole given buffer size. Drop the useless initialization, which just confuses readers. Signed-off-by:

Some fields in alsa_stream are the values we keep already in PCM runtime object, hence they are redundant. Use the standard PCM runtime values instead of the private copies. Signed-off-by:

The handling of SNDRV_PCM_TRIGGER_STOP at the trigger callback is incorrect: when the STOP is issued, the driver is supposed to drop the stream immediately. Meanwhile bcm2835 driver checks the DRAINING state and tries to issue some different command. This patch straightens things a bit, dropping the incorrect state checks. The draining behavior would be still not perfect at this point, but will be improved in a later patch. Signed-off-by:

The running flag of alsa_stream is basically useless. The running state is strictly controlled in ALSA PCM core side, hence the check in PCM trigger and close callbacks are superfluous. Also, the prefill ack at trigger start became superfluous nowadays with the ALSA PCM core update. Let's rip them off. Signed-off-by:

All the alsa_stream->open flag checks in the current code are redundant, and they cannot be racy. For the code simplification, let's remove the flag and its check. Signed-off-by:

bcm2835_audio_setup(), bcm2835_audio_flush_buffers() and bcm2835_audio_flush_playback_buffers() functions do implement nothing. Also, bcm2835_audio_set_ctls() is already called inside bcm2835_audio_set_params(), so the later call is superfluous. This patch removes these superfluous implementations. Signed-off-by:

In the current code, the mute control is dealt in a special manner, modifying the current volume and saving the old volume, etc. This is inconsistent (e.g. change the volume while muted, then unmute), and way too complex. Also, the whole volume handling code has conversion between ALSA volume and raw volume values, which can lead to another inconsistency and complexity. This patch simplifies these points: - The ALSA volume value is saved in chip->volume - volume->mute saves the mute state - The mute state is evaluated only when the actual volume is passed to the hardware, bcm2835_audio_set_ctls() Signed-off-by:

The avail_substreams bit mask is checked for the possible racy accesses, but this cannot happen in practice; i.e. the assignment and the check are superfluous. Let's rip them off. Signed-off-by:

The "IEC958 Playback Stream" control does basically the very same thing as "IEC958 Playback Default" redundantly. The former should have been stream-specific and restored after closing the stream, but we don't do in that way. Since it's nothing but confusion, remove this fake. Signed-off-by:

Takashi Iwai authored
snd-bcm2835 driver takes the lock with mutex_lock_interruptible() in all places, which don't make sense. Replace them with the simple mutex_lock(). Also taking a mutex lock right after creating it for each PCM object is nonsense, too. It cannot be racy at that point. We can get rid of it. Last but not least, initializing chip->audio_mutex at each place is error-prone. Initialize properly at creating the chip object in snd_bcm2835_create() instead. Signed-off-by:

PCI host drivers have already matched on compatible strings, so checking device_type is redundant. Also, device_type is considered deprecated for FDT though we've still been requiring it for PCI hosts as it is useful for finding PCI buses. Cc: devel@driverdev.osuosl.org Signed-off-by:

Rename 'pDot11dInfo', this member variable of the structure ieee80211_device causes a checkpatch issue, CamelCase naming. The member has been renamed 'dot11d_info' to clear this issue. This is a coding style change which should have no impact on runtime code execution. Signed-off-by:

The structure rt_dot11d_info contains a memeber variable 'enabled', which causes a checkpatch issue as it is declared as being of type bool. The type of the variable has been changed to a 'u8', to clear the issue. Additionally to aid searching for the member variable in code it has been renamed from 'enabled' to 'dot11d_enabled'. These are purely coding style changes which should not impact runtime code execution. Signed-off-by:

The function dot11d_init() was previously renamed to clear a style issue. Unfortunately the new name used, dot11d_init(), clashes with a sybmol which is exported with the same name. To correct this problem the function has been renamed to rtl8192u_dot11d_init(). Reported-by:
