[PATCH 33/33] ASoC: Convert to devm_ioremap_resource()

[PATCH 33/33] ASoC: Convert to devm_ioremap_resource()

[Thierry Reding]

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

It's probably too early to apply this yet since the first patch in the
series, which introduces the new function, hasn't been merged yet. I
seem to have handled this poorly, as David Miller already pointed out,
by not Cc'ing everyone involved on the first patch.

Oh, well.  Dropped then.  Acked-by instead.
