* ALSA: ppc/awacs: shut up maybe-uninitialized warningArnd Bergmann2016-07-051-0/+1
| | | | | | | | | | | | | | | 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.hBjorn Helgaas2016-02-051-1/+0
| | | | | | | | | | | 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 <bhelgaas@google.com>

* ALSA: ppc: keywest: Export I2C module alias informationJavier Martinez Canillas2015-08-251-0/+1
| | | | | | | | | | | The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added.

* ALSA: ppc: keywest: check if DEQ was already instantiatedWolfram Sang2015-05-291-1/+12
| | | | | | | | | | | | | 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.

* powerpc: Move Power Macintosh drivers to generic byteswappersDavid Gibson2015-03-231-29/+29
| | | | | | | | | | | | | | | | | | | | | | 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.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
