[PATCH] mmc: alcor: remove a redundant greater or equal to zero comparison
From: Colin King
Date: Mon Jul 01 2019 - 13:52:52 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
A greater or equal comparison on the unsigned int variable tmp_diff
is always true as unsigned ints are never negative. Hence the
comparison is redundant and can be removed.
Addresses-Coverity: ("Unsigned compared against 0")
