Subject: arm: mach-omap2: mux: fix buffer overrun
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3083314238afb593b598dca4bab4bb6ae09a6c82;p=linux.git

arm: mach-omap2: mux: fix buffer overrun

memcpy() copies 8 bytes too much (omap_mux_entry vs. omap_mux). Correct
by replacing memcpy() with struct assignment, which is safer.
