From: Bjorn Helgaas Date: Wed, 22 Mar 2006 07:20:28 +0000 (-0800) Subject: [PATCH] macintosh: tidy-up driver_register() return values X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d56a3e380085bf45cc2adba80c4e6490ba644231;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [PATCH] macintosh: tidy-up driver_register() return values 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. All callers of macio_register_driver() either ignore the return value or return it as the return value of a module_init() function.
