auxdisplay: img-ascii-lcd: 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/auxdisplay/img-ascii-lcd.ko | grep alias
$
After this patch:
$ modinfo drivers/auxdisplay/img-ascii-lcd.ko | grep alias
alias: of:N*T*Cmti,sead3-lcdC*
alias: of:N*T*Cmti,sead3-lcd
alias: of:N*T*Cmti,malta-lcdC*
alias: of:N*T*Cmti,malta-lcd
alias: of:N*T*Cimg,boston-lcdC*
alias: of:N*T*Cimg,boston-lcd
