Subject: spi: spi-mxs: Check the return value from stmp_reset_block()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8498bce934b864d609dab15a342bc47bb637c7f6;p=linux-beck.git

spi: spi-mxs: Check the return value from stmp_reset_block()

stmp_reset_block() may fail, so let's check its return value and propagate it in
the case of error.
