Subject: [PATCH v2 10/15] staging: fsl-mc: move rest of mc-bus.h to private header
From: Laurentiu Tudor <laurentiu.tudor@....com>
All the mc-bus.h contents is only used privately in the bus driver so
move everything to the private header and get rid of the mc-bus.h
header file.
Signed-off-by: Laurentiu Tudor <laurentiu.tudor@....com>
