The bug fix 352a2d5b "gpio/omap: ensure gpio context is initialised" has caused a new warning for omap1_defconfig: drivers/gpio/gpio-omap.c:1465:13: warning: 'omap_gpio_init_context' defined but not used [-Wunused-function] static void omap_gpio_init_context(struct gpio_bank *p) {} ^ The solution is to mark the stub function as 'static inline' so it gets left out of the build when unused.

Commit 7bce696b (gpio: Make gpio-msm-v1 into a platform driver, 2013-03-04) was based on an older kernel where __devinit still existed. Remove the erroneous __devinit marking.

This driver can be used on Xilinx ARM Zynq platform where in_be32/out_be32 functions are not implemented. Use __raw_readl/__raw_writel functions which are implemented on Microblaze and PowerPC. For ARM readl/writel functions are used instead. The correct way how to implement this is to detect endians directly on IP. But for the gpio case without interrupt connected(it means without interrupt logic) there are just 2 registers data and tristate where auto detection can't be done.

do_smart_update_queue() is called when an operation (semop, semctl(SETVAL), semctl(SETALL), ...) modified the array. It must check which of the sleeping tasks can proceed. do_smart_update_queue() missed a few wakeups: - if a sleeping complex op was completed, then all per-semaphore queues must be scanned - not only those that were modified by *sops - if a sleeping simple op proceeded, then the global queue must be scanned again And: - the test for "|sops == NULL) before scanning the global queue is not required: If the global queue is empty, then it doesn't need to be scanned - regardless of the reason for calling do_smart_update_queue() The patch is not optimized, i.e. even completing a wait-for-zero operation causes a rescan. This is done to keep the patch as simple as possible.
