When review device driver modules which attach to amba bus, found several modules are not using devm_*() apis to manage resource. As result, some drivers have memory leakage or missing iomem unmapping when rmmod module. And the code has many "goto" tags to handle different failures.
So this patch series is to convert to use devm_*() for moudules which are attached to amba bus to manage resource and get more robust and neat code.
Patch 0003 "drivers/rtc/rtc-pl031.c: Convert to use devm_*()" has been verified on 96boards Hikey. Other patches can pass building but have not really tested on hardware.
