Subject: i2c: core: disable runtime PM on adapter registration failure
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=3e2041ea586ae37fcea918ecb505ab9972a1201d;p=thirdparty%2Fkernel%2Flinux.git

i2c: core: disable runtime PM on adapter registration failure

Runtime PM is disabled by driver core when deregistering a device (and
on registration failure) but add an explicit disable to balance the
enable call when adapter registration fails for symmetry.

Fixes: 23a698fe65ec ("i2c: core: treat EPROBE_DEFER when acquiring SCL/SDA GPIOs")
