Rodriguez" Date: Wed, 3 Feb 2016 16:55:26 +1030 Subject: modules: fix modparam async_probe request From: Luis R. Rodriguez commit 4355efbd80482a961cae849281a8ef866e53d55c upstream. Commit f2411da746985 ("driver-core: add driver module asynchronous probe support") added async probe support, in two forms: * in-kernel driver specification annotation * generic async_probe module parameter (modprobe foo async_probe) To support the generic kernel parameter parse_args() was extended via commit ecc8617053e0 ("module: add extra argument for parse_params() callback") however commit failed to f2411da746985 failed to add the required argument. This causes a crash then whenever async_probe generic module parameter is used. This was overlooked when the form in which in-kernel async probe support was reworked a bit... Fix this as originally intended. Cc: Hannes Reinecke Cc: Dmitry Torokhov Signed-off-by: Luis R.
