Subject: gpu: nova-core: vbios: stop scanning at BIOS_MAX_SCAN_LEN
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fc7c1054b6f983ae2f3e100a24cc87908ae9f4b7;p=thirdparty%2Fkernel%2Flinux.git

gpu: nova-core: vbios: stop scanning at BIOS_MAX_SCAN_LEN

Current code lets `current_offset` go to `BIOS_MAX_SCAN_LEN` which is
one byte too far.
