Subject: checkpatch: make in_atomic ok in the core
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f4a8773676c21a68b0666fbe48af4fe1af89dfa9;p=linux-beck.git

checkpatch: make in_atomic ok in the core

We say that in_atomic() is ok in the core kernel, but then always report
it regardless of where in the kernel it is.  Keep quiet if it is used in
kernel/*.
