ALSA: ppc/awacs: shut up maybe-uninitialized warning

2016-07-05T06:35:49+00:00

The awacs sound driver produces a false-positive warning in ppc64_defconfig: sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': include/sound/control.h:219:9: warning: 'master_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] I haven't come up with a good way to rewrite the code to avoid the warning, so here is a bad one: I initialize the variable before the conditionall initialization so gcc no longer has to worry about it.

PCI: Remove includes of asm/pci-bridge.h

2016-02-05T22:29:28+00:00

Drivers should include asm/pci-bridge.h only when they need the arch- specific things provided there. Outside of the arch/ directories, the only drivers that actually need things provided by asm/pci-bridge.h are the powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*. Remove the includes of asm/pci-bridge.h from the other drivers, adding an include of linux/pci.h if necessary. Signed-off-by: Bjorn Helgaas

ALSA: ppc: keywest: check if DEQ was already instantiated

2015-05-29T10:54:10+00:00

Due to changes in i2c-powermac, for some Macs the DEQ is instantiated now in i2c-powermac while some need the instantiation here in the keywest sound driver. The proper fix is to convert this driver to AOA. Until then support both ways of instantiation. Before this patch, some Macs lost sound because the sound driver failed when instantiating the DEQ for the second time. Signed-off-by: Wolfram Sang Tested-by: Dan DeVoto Signed-off-by: Takashi Iwai

ALSA: ppc: keywest: drop using attach adapter

2015-05-18T09:25:44+00:00

As we now have deferred probing, we can use a custom mechanism and finally get rid of this legacy interface from the i2c core. Signed-off-by: Wolfram Sang Tested-by: Dan DeVoto Tested-by: Mark Elliott Signed-off-by: Takashi Iwai

powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40+00:00

ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

ALSA: Include linux/io.h instead of asm/io.h

ALSA: Deletion of checks before the function call "iounmap"

2015-01-04T14:13:45+00:00

The iounmap() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Takashi Iwai

ALSA: ps3: Remove unnecessary snd_pcm_lib_preallocate_free_for_all()

2015-01-02T15:34:57+00:00

The ALSA core takes care that all preallocated memory is freed when the card (and the PCM) itself is freed. There is no need to do this manually in the driver. Signed-off-by: Lars-Peter Clausen Signed-off-by: Takashi Iwai
