Subject: [RFC PATCH] mmc: dw_mmc: remove redundant num_slots check
Date: Thu, 21 Jan 2016 15:52:49 +0800 [thread overview]
Message-ID: <1453362769-16223-1-git-send-email-shawn.lin@rock-chips.com> (raw)
num_slots comes from pdata if existing, otherwise from
dw_mci_parse_dt which make it at least one slot. If
num_slots is less than 1 for the existing pdata case,
current code return -ENODEV. But dw_mci_probe seems to
treat this a optional case as it will call SDMMC_GET_SLOT_NUM
if no slot assigned.
