From: Stephen Boyd Date: Sun, 26 Jun 2016 05:38:21 +0000 (-0700) Subject: usb: ulpi: Automatically set driver::owner with ulpi_driver_register() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1ebe88d38ddec6b05f7b5e64acef30a98a4ad17e;p=linux-beck.git usb: ulpi: Automatically set driver::owner with ulpi_driver_register() Let's follow other driver registration functions and automatically set the driver's owner member to THIS_MODULE when ulpi_driver_register() is called. This allows ulpi driver writers to forget about this boiler plate detail and avoids common bugs in the process.
