Ben Wolsieffer a4b4648c01 regmap: prevent noinc writes from clobbering cache
[ Upstream commit 984a4afdc8 ]

Currently, noinc writes are cached as if they were standard incrementing
writes, overwriting unrelated register values in the cache. Instead, we
want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

Fixes: cdf6b11daa ("regmap: Add regmap_noinc_write API")
