From: Roman Stratiienko <roman.stratiie...@globallogic.com>
Since kernel v5.0 upstream commit 96d4f267e40f
("Remove 'type' argument from access_ok() function")
access_ok() funcion takes only 2 parameters
Change access_rok and access_wok wrappers for kernels
starting from v5.0, and preserve them for earlier versions
Also nitpicking: I would refer to access_ok in the subject line as well. This is
already a single-topic patch, so that works out nicely.
