5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf W_Armin@gmx.de
commit fe0e04cf66a12ffe6d1b43725ddaabd5599d024f upstream.
If platform_profile_register() fails, the driver does not propagate the error, but instead probes successfully. This means when the driver unbinds, the a warning might be issued by platform_profile_remove().
Fix this by propagating the error back to the caller of surface_platform_profile_probe().
Compile-tested only.
