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 Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
