Fix characters being dropped by n_tty_write() due to a failure to
check the return value of tty_put_char() in do_output_char().
Characters are currently being dropped by write if a tty driver claims
to have write room available, but still fails to buffer any data (e.g.

The current runtime suspend implementation is broken in several ways:
Firstly, it buffers only the first write request being made while
suspended -- any further writes are silently dropped.
Secondly, writes being dropped also leak write urbs which are never

Then you should split this into two patches.

When the device is unplugged, the driver would try to disable the
device. Add checking the flag of RTL8152_UNPLUG to skip setting
the device when it is unplugged. This could shorten the time of
unloading the driver.

I did set the scsi_logging_level as you wrote, but it still resulted
into exactly the same dmesg (resp. sudo journalctl -b 0) output with the
entire patchset (including the scmd-eh_eflags = 0;). Except for the
reverted do nothings, for course.
However, I did miss to mention the following
If acm_submit_read_urbs() fails in acm_port_activate(), error handling
code calls usb_autopm_put_interface() while it is already called
before acm_submit_read_urbs(). The patch reorganizes error handling code
to avoid double decrement of USB interface's PM-usage counter.
