Subject: OPP: Return correct value in dev_pm_opp_get_level
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b7277e02dabba2a9921a7f4761ae6e627e7297a;p=thirdparty%2Flinux.git

OPP: Return correct value in dev_pm_opp_get_level

Commit 073d3d2ca7d4 ("OPP: Level zero is valid") modified the
documentation for this function to indicate that errors should return a
non-zero value to avoid colliding with the OPP level zero, however
forgot to actually update the return.

No in-tree kernel code depends on the error value being 0.

Fixes: 073d3d2ca7d4 ("OPP: Level zero is valid")
