[PATCH 5.15 136/148] i2c: imx: If pm_runtime_get_sync() returned 1 device access is possible

[Greg Kroah-Hartman]

From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>

[ Upstream commit 085aacaa73163f4b8a89dec24ecb32cfacd34017 ]

pm_runtime_get_sync() returning 1 also means the device is powered. So
resetting the chip registers in .remove() is possible and should be
done.
