-Subject: [PATCH] spi: Dont call prepare/unprepare transfer if not populated
-
-Currently the prepare/unprepare transfer are called unconditionally.
-The assumption is that every driver using the spi core queue infrastructure
-has to populate the prepare and unprepare functions. This encourages
-drivers to populate empty functions to prevent crashing.
-This patch prevents the call to prepare/unprepare if not populated.
