2014-07-22misc: vexpress: Fix sparse non static symbol warningsWei Yongjun
Fixes the following sparse warnings: drivers/misc/vexpress-syscfg.c:133:22: warning: symbol 'vexpress_syscfg_regmap_config' was not declared. Should it be static? drivers/misc/vexpress-syscfg.c:279:5: warning: symbol 'vexpress_syscfg_probe' was not declared. Should it be static?

2014-07-09mfd: vexpress: fix error handling vexpress_syscfg_regmap_init()Dan Carpenter
This function should be returning an ERR_PTR() on failure instead of NULL. Also there is a use after free bug if regmap_init() fails because we free "func" and then dereference doing the return.

2014-05-15mfd: vexpress: Define the device as MFD cellsPawel Moll
This patch - finally, after over 6 months! :-( - addresses Samuel's request to split the vexpress-sysreg driver into smaller portions and define the device in a form of MFD cells: * LEDs code has been completely removed and replaced with "gpio-leds" nodes in the tree (referencing dedicated GPIO subnodes in sysreg - bindings documentation updated); this also better fits the reality as some variants of the motherboard don't have all the LEDs populated * syscfg bridge code has been extracted into a separate driver (placed in drivers/misc for no better place) * all the ID & MISC registers are defined as sysconf making them available for other drivers should they need to use them (and also to the user via /sys/kernel/debug/regmap which can be helpful in platform debugging) Signed-off-by: Pawel Moll <pawel.moll@arm.com> Acked-by: Lee Jones <lee.jones@linaro.org>
