ACPI: Video: Increase buffer size for writes to brightness proc file.
In order to be able to write the value "100" to /proc/acpi/video/.../brightness, we have to allocate 5 bytes: 4 characters will be written (1, 0, 0 plus null byte), and 1 byte should be buffer for a terminating NULL character. http://bugzilla.kernel.org/show_bug.cgi?id=9278 Signed-off-by: Danny Baumann <dannybaumann@web.de> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
