From: Bjorn Helgaas Date: Wed, 22 Mar 2006 07:20:27 +0000 (-0800) Subject: [PATCH] powerpc: tidy-up of_register_driver()/driver_register() return values X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ea671a12f66b9d4d0f35fce957a71a6849295f2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [PATCH] powerpc: tidy-up of_register_driver()/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. Nobody uses the return value of of_register_driver() anyway.
