Subject: ncr5380: Fix bus phase in do_abort()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f35d34744c85b2ea31a3fe624616c10229ff1fb3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ncr5380: Fix bus phase in do_abort()

NCR5380_poll_politely() returns either 0 (success) or -ETIMEDOUT. However,
in do_abort(), the return value is incorrectly taken to be the status
register value. This means that the bus is put into DATA OUT phase instead
of MESSAGE OUT. Fix this.
