Subject: [PATCH v1 43/63] Input: atmel_mxt_ts: update stale use_retrigen_workaround flag

From: Balasubramani Vivekanandan <balasubramani_vivekanandan@...tor.com>

If after configuration update, retrigen status is enabled, the
mxt_check_retrigen() function, called after configuration update,
does not clear the use_retrigen_workaround flag, if it was previously
set.
