Re: [PATCH 0/6] video: udlfb: (not only) Logging cleanup

This patchset is a side product of debugging on unreliable USB host
where devices saw a lot of disconnects. It turned out that udlfb
logging is just too noisy to be usefull as produced syslog is hard
to read.

Hence this attempt to clean things up.

Comments and suggestions welcome and appreciated, as always.

Ladislav Michl (6):
  video: udlfb: Do not name private data 'dev'

This patch no longer applies cleanly after following patches:

11ab5a6 video: udlfb: Delete an unnecessary return statement in two functions
74fb251 video: udlfb: Improve a size determination in dlfb_alloc_urb_list()

have been merged into fbdev-for-next.

  video: udlfb: Remove unnecessary 'return'

I've already applied identical patch from Markus which was posted
some time earlier.

  video: udlfb: Remove unnecessary local variable

Please make this patch #1 in the series.

  video: udlfb: Delete error messages for failed allocations

In one place this patch removes the information about the device for
which the allocation fails and generally I would prefer to still have
the information about devices for which allocation fails (so please
consider dropping this patch and converting relevant places to use
dev_*() logging functions).

  video: udlfb: Remove redundant gdev variable

Please make this patch #2 in the series.

  video: udlfb: Switch from the pr_*() to the dev_*() logging functions

This patch also removes some log entries completely and I would prefer
such changes to be split into a separate pre-patch (please also give
a valid rationale for the removal in the patch description).
