Subject: [PATCH] of_path: only handle no driver for device if it is on a bus
Date: Thu, 12 Jan 2017 12:20:05 +0000 [thread overview]
Message-ID: <20170112122005.805-1-abbotti@mev.co.uk> (raw)
This fixes a regression in __of_find_path() for flash devices created by
the cadence-quadspi driver, which do not have 'dev->driver' set. Such
devices do not have 'dev->bus' set either, so we can use that to qualify
the existing test.
