[PATCH 5.4 36/50] hexagon: clean up ioremap

From: Greg Kroah-Hartman
Date: Fri May 08 2020 - 08:53:41 EST


From: Christoph Hellwig <hch@xxxxxx>

commit ac32292c8552f7e8517be184e65dd09786e991f9 upstream.

Use ioremap as the main implemented function, and defined
ioremap_nocache to it as a deprecated alias.
