From: Bjorn Helgaas Date: Sat, 25 Mar 2006 11:07:19 +0000 (-0800) Subject: [PATCH] EISA: tidy-up driver_register() return value X-Git-Tag: v2.6.17-rc1~816 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=c2f6fabb2ed3b869bc254c6cdc73d6beaaaf700f;p=linux-2.6-omap-h63xx.git [PATCH] EISA: tidy-up driver_register() return value Remove the assumption that driver_register() returns the number of devices bound to the driver. In fact, it returns zero for success or a negative error value.
