Subject: [PATCH] bcm43xx: Add firmware version printout
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1ef4583ee3e1efab83d05b6ccdad378c9caaa95f;p=linux-beck.git

[PATCH] bcm43xx: Add firmware version printout

This patch prints microcode revision, patchlevel, date and time to
KERN_INFO. Also, version 4.xx microcodes (rev>0x128) will be rejected
by the driver, because they still do not work.
