[PATCH 10/31] staging: bcm2835-camera: Reduce length of enum names

Stefan Wahren wahrenst at gmx.net
Thu Jun 27 18:56:07 UTC 2019


From: Dave Stevenson <dave.stevenson at raspberrypi.org>

We have numerous lines over 80 chars, or oddly split. Many
of these are due to using long enum names such as
MMAL_COMPONENT_CAMERA.
Reduce the length of these enum names.
