Subject: mmc: dw_mmc: fix the wrong AND operation
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ca2ec9adc951cc3798e9b0c3773cdcc613232a22;p=project%2Fbcm63xx%2Fu-boot.git

mmc: dw_mmc: fix the wrong AND operation

These condition checking are wrong.
Original Author's intention might be "&" instead of "&&".
It can know whether receive or transmit data request with
BIT[4]/BIT[5] of RINTSTS register.
