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

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

ALSA: powermac: Deletion of an unnecessary check before the function call "pci_dev_put"

2014-11-17T12:52:45+00:00
