[Nouveau] [PATCH] drm/nouveau/bios: fix incorrect kfree in platform_init

[Roy Spliet]

(re-sending as plain text)

NACK. The before and after of this patch are functionally identical. The 
if-block returns unconditionally ("return priv;"), so the kfree will 
only ever be reached if the condition in the if-statement evaluates to 
false. Explicitly writing out an else-block is thus superfluous.
