rtc: asm9260: rework locking The rtc-asm9260 driver uses a discrete spinlock (wrongly uninitialized). Use the rtc mutex to lock mmio accesses instead. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

rtc: asm9260: remove incorrect __init/__exit annotations The probe and remove callbacks of the platform driver are marked __init and __exit, respectively. However, this is not a correct way to annotate them, as it will result in those sections to be discarded at link time or after boot, while we can actually call them again based on manual unbinding, or deferred probing. Kbuild warns about the problem: WARNING: drivers/rtc/rtc-asm9260.o(.data+0x0): Section mismatch in reference from the variable asm9260_rtc_driver to the function .init.text:asm9260_rtc_probe() This removes the annotations, so we no longer branch into missing code and avoid the warning.

rtc: asm9260: fix module autoload If the driver is built as a module, autoload won't work because the module alias information is not filled so user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/rtc/rtc-asm9260.ko | grep alias $ After this patch: $ modinfo drivers/rtc/rtc-asm9260.ko | grep alias alias: of:N*T*Calphascale,asm9260-rtcC* alias: of:N*T*Calphascale,asm9260-rtc Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
