Subject[PATCH AUTOSEL for 3.18 36/59] platform/x86: sony-laptop: Fix error handling in sony_nc_setup_rfkill()
Date
From: Markus Elfring <elfring@users.sourceforge.net>

[ Upstream commit f6c8a317ab208aee223776327c06f23342492d54 ]

Source code review for a specific software refactoring showed the need
for another correction because the error code "-1" was returned so far
if a call of the function "sony_call_snc_handle" failed here.
Thus assign the return value from these two function calls also to
the variable "err" and provide it in case of a failure.

Fixes: d6f15ed876b83a1a0eba1d0473eef58acc95444a ("sony-laptop: use soft rfkill status stored in hw")
