Subject[PATCH] sdhci: remove redundant check of zero slots
Date
From: Colin Ian King <colin.king@canonical.com>

Slots can never be zero, PCI_SLOTS_INFO_SLOTS returns a value in the
range 0..7; slots is one more than this, 1..8 so cannot be zero and
so the zero check is redundant and can be removed.

Detected by CoverityScan, CID#744269 ("Logically Dead Code")
