Subject: USB: mos7720: remove incorrect read-urb check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6d0f41abae30112b3cdca62c09370cc8801ee1f5;p=linux-beck.git

USB: mos7720: remove incorrect read-urb check

Remove incorrect and unnecessary check for port->read_urb which is not
set to NULL, contrary to what seems to be assumed, when urb is killed.

Compile only-tested.
