The driver has a platform device ID table with multiple device entries,
each setting a different register address in its driver_data to control
the WLED brightness.
But the driver doesn't export these as aliases with MODULE_DEVICE_TABLE()
when the driver is built as a module, instead it just has a single alias
using MODULE_ALIAS("platform:da9052-backlight"). That is clearly wrong
since there isn't a "da9052-backlight" in the platform device ID table,
so if that device name is used, the device won't even match the driver.
So instead of having a wrong alias, export the ones in the dev ID table.
Before this patch:
$ modinfo drivers/video/backlight/da9052_bl.ko | grep alias
alias: platform:da9052-backlight
After this patch:
$ modinfo drivers/video/backlight/da9052_bl.ko | grep alias
alias: platform:da9052-wled3
alias: platform:da9052-wled2
alias: platform:da9052-wled1
