[PATCH 12/16] staging: gasket: core: factor out generic device remove code from PCI

From: Todd Poynor
Date: Thu Aug 09 2018 - 23:22:06 EST


From: Todd Poynor <toddpoynor@xxxxxxxxxx>

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