Subject: drivers: staging: Drop unlikely before IS_ERR(_OR_NULL)
X-Git-Tag: v4.14-rc1~4839^2~291
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7f44cb0ba88b40c09c5bdfc46186e09f42b1a9b0;p=platform%2Fkernel%2Flinux-rpi.git

drivers: staging: Drop unlikely before IS_ERR(_OR_NULL)

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
is no need to do that again from its callers. Drop it.

This also replaces an IS_ERR(x) + (x == NULL) check to IS_ERR_OR_NULL
check.
