The first three (7266,7791,7793) were not already holding a lock on direct mode, so this will be a change in behavior for those drivers. The last four (7476,7887,7923,799x) were already locking so these are migrations to the claim/release helper functions. Worth noting: This does not clean up all mlock (ab-)uses in ad799x. This driver is still using mlock in a few other places not associated with locking down direct mode.
