From: David Kilroy Date: Thu, 18 Jun 2009 22:21:21 +0000 (+0100) Subject: orinoco: use dev_err in early initialisation routines X-Git-Tag: v2.6.32-rc1~703^2~751 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a3f47b9c2ada45ffacc8f2b54507221a1ba8eb10;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git orinoco: use dev_err in early initialisation routines This allows us to use determine_fw_capabilities, orinoco_hw_read_card_setting and orinoco_hw_allocate_fid prior to netdev registration. Since dev_dbg only prints if DEBUG is defined (or dynamic debug is enabled), move a couple of the more useful prints up to info. Signed-off-by: David Kilroy Signed-off-by: John W.
