-Subject: [PATCH] staging: vc04_services: isp: Make all references to
- bcm2835_isp_fmt const
-
-The array of potential formats and their configuration should be const.
-Rework all accesses so that this is possible.
-
-The list of supported formats was taking a copy of entries from this table.
-This is unnecessary, therefore allocate an array of pointers instead of
-an array of entries.
