Subject: [PATCH] pcnet32: remove superfluous NULL pointer check in pcnet32_probe1()
Move the debug printk() into the proper place and remove superfluous
NULL pointer check in pcnet32_probe1().
This takes care of the following entry from Dan's list:
drivers/net/pcnet32.c +1889 pcnet32_probe1(298) warning: variable derefenced before check 'pdev'

Applied, but please CC: netdev@vger.kernel.org for all future
network driver patches so that it gets properly tracked in
patchwork. Thanks!
