From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The macro ATMEL_TC_ETRGEDG_NONE is defined as 0 << 8 which is zero and
hence the check cmr & ATMEL_TC_ETRGEDG_NONE can never be true. Since
*action is already assigned MCHP_TC_SYNAPSE_ACTION_NONE then this check
and set is redundant dead code and can be removed.
Addresses-Coverity: ("Logically dead code")
