The struct rkisp1_cif_isp_ctk_config represents a 3x3 matrix
and an offset vector for the color correction. It is nicer
to represent those with a 3x3 array and a 3-array fields.
- First patch repalces 9 fields 'coeff*' with one field coeff[3][3]
- Second patch replaces 3 fields 'ct_offset_{rgb}' with one field 'ct_offset[3]'
Dafna Hirschfeld (2):
media: staging: rkisp1:: replace 9 coeff* fields with a 3x3 array
media: staging: rkisp1: replace 3 fields 'ct_offset_*' with one array
