mmc: alcor: remove a redundant greater or equal to zero comparison
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") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
