Subject: [PATCH 12/16] staging: gasket: core: factor out generic device remove code from PCI
Date: Thu,  9 Aug 2018 20:21:07 -0700
Message-ID: <20180810032111.197743-13-toddpoynor@gmail.com> (raw)
In-Reply-To: <20180810032111.197743-1-toddpoynor@gmail.com>

From: Todd Poynor <toddpoynor@google.com>

Separate code for generic parts of gasket device removal sequence from
the PCI device removal code, in prep for non-PCI devices later.
