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

2017-06-13T13:29:19Z

[ Upstream commit b268c34e5ee92a4cc3099b0caaf26e6bfbdf0f18 ] 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.

powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40Z

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"

2015-01-04T14:13:45Z

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()

2015-01-02T15:34:57Z

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"

2014-11-17T12:52:45Z

of: Migrate of_find_node_by_name() users to for_each_node_by_name()

2014-06-26T16:12:24Z

There are a bunch of users open coding the for_each_node_by_name() by calling of_find_node_by_name() directly instead of using the macro. This is getting in the way of some cleanups, and the possibility of removing of_find_node_by_name() entirely. Clean it up so that all the users are consistent.
