This driver has been converted to use regulator core's simplified DT
parsing code. So the match_init_data/match_of_node functions are not
necessary now, remove them.

I already reported this as a bug in clang, but it may take a
while to fix it. As I have not been able to come up with any
reasonable workaround, I would just disable compilation here.

The mutex for the regulator_dev must be controlled by the caller of
the regulator_notifier_call_chain(), as described in the comment
for that function.

Failure to mutex lock and unlock surrounding the notifier call results
in a kernel WARN_ON_ONCE() which will dump a backtrace for the
regulator_notifier_call_chain() when that function call is first made.
The mutex can be controlled using the regulator_lock/unlock() API.

  The resume fix is a cosmetic removal of a warning with an incorrect

  The other eight patches correct a thinko in Christoph Hellwig's DMA

  masks meaning they bounce any page over 4GB before sending it to the
