Subject: [PATCH] mfd: sm501: Add check for platform_driver_register()
Git-commit: 8325a6c24ad78b8c1acc3c42b098ee24105d68e5
Patch-mainline: v6.1-rc1
References: git-fixes
As platform_driver_register() can return error numbers,
it should be better to check platform_driver_register()
and deal with the exception.
Fixes: b6d6454fdb66 ("[PATCH] mfd: SM501 core driver")
