[PATCH] rtc: asm9260: fix module autoload

From: Javier Martinez Canillas
Date: Fri Oct 14 2016 - 09:23:42 EST


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
