Subject: staging: comedi: serial2002: remove pr_err() noise in serial2002_read()
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=7e32f5ada58a15c299143eb98af7e784334d4719;p=~shefty%2Frdma-dev.git

staging: comedi: serial2002: remove pr_err() noise in serial2002_read()

This pr_err() is just added noise, the user can't do anything about it.
Just remove it.

Since this is the only pr_level() message in the driver, also remove
the pr_fmt() macro.
