Subject: tty: serial: bfin_sport_uart: fix signedness error
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=940f3be4058e0aff0505fd6f68e29e547e10e552;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

tty: serial: bfin_sport_uart: fix signedness error

sport->port.irq is unsigned, check for <0 doesn't make sense.
Explicitly cast it to int to check for error.
