[PATCH 11/15] staging: gasket: core: remove sysfs setup and cleanup callbacks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Todd Poynor <toddpoynor@xxxxxxxxxx>

Gasket device drivers now call into the gasket framework to initialize
and de-initialize, rather than the other way around.  The calling code
can perform sysfs setup and cleanup actions without callbacks from the
framework.  Remove the sysfs setup and cleanup callbacks.
