Subject: gpio: cros-ec: provide ID table for avoiding fallback match
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=782f4e47ffc19622bf80b3c0cf9cadd2b0b9a644;p=linux.git

gpio: cros-ec: provide ID table for avoiding fallback match

Instead of using fallback driver name match, provide ID table[1] for the
primary match.  Also allow automatic module loading by adding
MODULE_DEVICE_TABLE().
