Hmm... patch 06/14 needs this one to compile... This patch should have been added before 06/14...
Also, this is just a series of magic numbers. Could you please put a generic
comment about the meaning of those numbers, better specifying what those tables
are meant to and how are they handled?
Also, instead of just having a magic sequence of numbers, is better to have the
struct definition there, and put it into a nicer format.
So, instead of:
/*
* CFA Filter Coefficient Table
*
*/
static u32 cfa_coef_table[] = {
#include "cfa_coef_table.h"
};
You should do something like:
/*
* Color Filter Array (CFA) Coefficient Table
*
* This table specifies coefficients for a filter that ...
*
*/
static u32 cfa_coef_table[] = {
0, 247, 0, 244, 247, 36, 27, 12,
0, 27, 0, 250, 244, 12, 250, 4,
...
};
Cheers,
Mauro
