Subject: sh: perf events: Fix up uninitialized variable warning.
X-Git-Tag: firefly_0821_release~9833^2~3643^2~62^2~15
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8820002c18cd3167d2800c002f13d78fa0325402;p=firefly-linux-kernel-4.4.55.git

sh: perf events: Fix up uninitialized variable warning.

'config' can be unintialized, and although it's not really an error, it
still manages to trigger the -Werror with certain toolchains. Initialize
it early to shut up gcc.
