2012-10-07drivers/net/irda/sh_sir.c: fix error return codePeter Senna Tschudin1-2/+3
The function sh_sir_probe() return 0 for success and negative value for most of its internal tests failures. There are two exceptions that are error cases going to err_mem_*:. For this two cases, the function abort its success execution path, but returns non negative value, making it dificult for a caller function to notice the error. This patch fixes the error cases that do not return negative values. This was found by Coccinelle, but the code change was made by hand. This patch is not robot generated. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.

Pull first batch of arm-soc cleanups from Olof Johansson: "These cleanups are basically all over the place. The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series. A significant number of lines get removed here, in particular because the ixp2000 and ixp23xx platforms get removed. These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform. Many good cleanups also went into the at91 and omap platforms, as has been the case for a number of releases."

Current ARM7 Cirrus Logic product line contains only 3 cpu. EP7312 - Fully functional. EP7309 - Missing SDRAM interface. EP7311 - Missing DAI. It makes no sense to separate the header files to identify these differences, it is only necessary to keep in mind the presence or lack of any features of a specific CPU when writing code.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

Pull ARM platform updates from Russell King: "This covers platform stuff for platforms I have a direct interest in (iow, I have the hardware). Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts."
