[PATCH 01/10] staging: gasket: save struct device for a gasket device

From: Todd Poynor
Date: Thu Jul 26 2018 - 23:08:07 EST


From: Todd Poynor <toddpoynor@xxxxxxxxxx>

Save the struct device pointer to a gasket device in gasket's metadata,
to facilitate use of standard logging calls and in anticipation of
non-PCI gasket devices in the future.
