Subject: [PATCH 5.0 077/123] mtd: maps: physmap: Store gpio_values correctly
From: Chris Packham <chris.packham@...iedtelesis.co.nz>
commit 64d14c6fe040361ff6aecb825e392cf97837cd9e upstream.
When the gpio-addr-flash.c driver was merged with physmap-core.c the
code to store the current gpio_values was lost. This meant that once a
gpio was asserted it was never de-asserted. Fix this by storing the
current offset in gpio_values like the old driver used to.
Fixes: commit ba32ce95cbd9 ("mtd: maps: Merge gpio-addr-flash.c into physmap-core.c")
