Subject: dsa: mv88e6xxx: Make mv88e6xxx_wait() timeout verbose
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=30853553c0e056403e1d6b2915a903401647839a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

dsa: mv88e6xxx: Make mv88e6xxx_wait() timeout verbose

When mv88e6xxx_wait() returns a timeout, something bad has
happened. Make sure it is noticed by logging an error.
