MIPS: Yosemite, Emma: Fix off-by-two in arcs_cmdline buffer size check
Cause is a misplaced bracket. The code strlen(buf+1) will be two bytes less than strlen(buf)+1 The +1 is in this code to reserve space for an additional space character. [ralf@linux-mips.org: Thomas' original patch fixed the issue only for Yosemite but the same bug exists also in Emma.] Signed-off-by: Thomas Jarosch <thomas.jarosch@intra2net.com> Patchwork: https://patchwork.linux-mips.org/patch/2861/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
