Subject: bus: brcmstb_gisb: Use register offsets with writes too
From: Doug Berger <opendmb@xxxxxxxxx>
[ Upstream commit 856c7ccb9ce7a061f04bdf586f649cb93654e294 ]
This commit corrects the bug introduced in commit f80835875d3d
("bus: brcmstb_gisb: Look up register offsets in a table") such
that gisb_write() translates the register enumeration into an
offset from the base address for writes as well as reads.
Fixes: f80835875d3d ("bus: brcmstb_gisb: Look up register offsets in a table")
