Subject: [PATCH] Input: tca8418: remove redundant variable max_keys

From: Colin Ian King <colin.king@...onical.com>

Variable max_keys is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
variable 'max_keys' set but not used [-Wunused-but-set-variable]
