Subject: USB: serial: io_ti: bind to interface after fw download
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e35d6d7c4e6532a89732cf4bace0e910ee684c88;p=linux-beck.git

USB: serial: io_ti: bind to interface after fw download

Bind to the interface, but do not register any ports, after having
downloaded the firmware. The device will still disconnect and
re-enumerate, but this way we avoid an error messages from being logged
as part of the process:

io_ti: probe of 1-1.3:1.0 failed with error -5
