Subject: driver-core: Allow additional parameters for module_driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cd4946188aac597d187a765127fd26fa3644c29f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

driver-core: Allow additional parameters for module_driver

Allow module_driver take additional parameters which will be passed to the
register and unregister function calls. This allows it to be used in cases
where additional parameters are required (e.g. usb_serial_register_drivers).
