* staging: Remove OOM message after input_allocate_deviceJoe Perches2013-10-291-2/+0
| | | | | | | | | Emitting an OOM message isn't necessary after input_allocate_device as there's a generic OOM and a dump_stack already done. Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The ones converted in this branch are: - bcm2835 - cns3xxx - sirf - nomadik - msx - spear - tegra - ux500 We're getting close to having most of them converted! One of the larger platforms remaining is Samsung Exynos, and there are a bunch of supporting patches in this merge window for it. There was a patch in this branch to a early version of multiplatform conversion, but it ended up being reverted due to need of more bake time. The revert commit is part of the branch since it would have required rebasing multiple dependent branches and they were stable by then" * tag 'multiplatform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (70 commits) mmc: sdhci-s3c: Fix operation on non-single image Samsung platforms clocksource: nomadik-mtu: fix up clocksource/timer Revert "ARM: exynos: enable multiplatform support" ARM: SPEAr13xx: Fix typo "ARCH_HAVE_CPUFREQ" ARM: exynos: enable multiplatform support rtc: s3c: make header file local mtd: onenand/samsung: make regs-onenand.h file local thermal/exynos: remove unnecessary header inclusions mmc: sdhci-s3c: remove platform dependencies ARM: samsung: move mfc device definition to s5p-dev-mfc.c ARM: exynos: move debug-macro.S to include/debug/ ARM: exynos: prepare for sparse IRQ ARM: exynos: introduce EXYNOS_ATAGS symbol ARM: tegra: build assembly files with -march=armv7-a ARM: Push selects for TWD/SCU into machine entries ARM: ux500: build hotplug.o for ARMv7-a ARM: ux500: move to multiplatform ARM: ux500: make remaining headers local ARM: ux500: make irqs.h local to platform ARM: ux500: get rid of <mach/[hardware|db8500-regs].h> ...
| * staging: ste_rmi4: kill platform_data hackArnd Bergmann2013-04-081-13/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is only one instance of the platform data for synaptics_i2c_rmi4 in the mainline kernel, so there is no point of pretending its variable here. The only member that has a dependency on the platform is actually the interrupt number, and there is a field in the i2c_client structure that gets initialized from the board info, so we can trivially move the board_into into the platform without knowledge of the platform_data structure.

* staging: Remove unnecessary OOM messagesJoe Perches2013-02-111-12/+6
| | | | | | | | | | | | | | | | | alloc failures already get standardized OOM messages and a dump_stack. For the affected mallocs around these OOM messages: Converted kzallocs with multiplies to kcalloc. Converted kmallocs with multiplies to kmalloc_array. Converted a kmalloc/strlen/strncpy to kstrdup. Moved a spin_lock below a removed OOM message and removed a now unnecessary spin_unlock. Neatened alignment and whitespace.

| * Staging: ste_rmi4: use after input_unregister_device()Dan Carpenter2011-01-201-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The original code called input_free_device(rmi4_data->input_dev) after input_unregister_device(rmi4_data->input_dev) and that's a double free. This is described in the comments to input_unregister_device(). The normal way to handle this is to make input_register_device() the last function in the probe which can fail. That way you can avoid the call to input_unregister_device() entirely. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
