Subject: [PATCH v2 11/18] dmaengine: idxd: idxd: move remove() bits for idxd 'struct device' to device.c
Date: Wed, 14 Jul 2021 16:21:24 -0700	[thread overview]
Message-ID: <162630488467.631529.4445840639623548181.stgit@djiang5-desk3.ch.intel.com> (raw)
In-Reply-To: <162630468448.631529.1963704964865951650.stgit@djiang5-desk3.ch.intel.com>

Move the code related to a ->remove() function for the idxd
'struct device' to device.c to prep for the idxd device
sub-driver in device.c.
