Subject: kernel/panic.c: reduce 1 byte usage for print tainted buffer
X-Git-Tag: next-20131105~2^2~16
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=74b173e3ba19fb4682646fbc18ff0d5a88b129cd;p=karo-tx-linux.git

kernel/panic.c: reduce 1 byte usage for print tainted buffer

sizeof("Tainted: ") already counts '\0', and after first sprintf(), 's'
will start from the current string end (its' value is '\0').

So need not add additional 1 byte for maximized usage of 'buf' in
print_tainted().
