Subject: staging: unisys: remove goto in get_vbus_header_info
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f748f64f0605f5a236aee103b75ec48075d2c4fa;p=linux-beck.git

staging: unisys: remove goto in get_vbus_header_info

Remove the rc, the = -1, and all the goto mess here and just return
directly with a meaningful error number.

The caller only cares about success/failure right now, that needs to be
addressed in a later patch series.
