X-Git-Tag: v5.10.7~1469^2~432 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f718f6c8b7fb0290e97419d4647fba5cde5dff33;p=platform%2Fkernel%2Flinux-rpi.git media: staging: rkisp1: set "*_data_tbl" fields in rkisp1_cif_isp_lsc_config as 2D arrays Currently the fields '*_data_tbl' in the struct 'rkisp1_cif_isp_lsc_config' are one dimensional arrays of size 290. The entries are accessed in a nested loop by summing two indexes for the rows and columns. Therefore it fits better to define the arrays as two dimensional arrays of size 17x17.
