Hi,

I believe there maybe a typo in the name of an array being assigned, 
introduced in commit:

     media: staging/intel-ipu3: css: Compute and program ccs


The issue is as follows in function imgu_css_acc_process_lines in 
drivers/staging/media/ipu3/ipu3-css-params.c

                         if (pl_idx == 0)
                                 /* First process line */
                                 p_pl[pl_idx].lines = first_process_lines;
                         else if (pl_idx == num_of_sets - 1)
                                 /* Last in grid */
                                 p_pl[pl_idx].lines = 
last_process_lines_in_grid;
                         else if (pl_idx == num_of_process_lines - 1)
                                 /* After the grid */
                                 p_pl[pl_idx].lines = 
process_lines_after_grid;
                         else
                                 /* Inside the grid */
                                 p_pl[pl_idx].lines = process_lines;

                         if (p_tr) {
                                 p_pl[pl_idx].cfg_set = pl_cfg_set;
                                 pl_cfg_set = 1 - pl_cfg_set;
                         }
                         pl_idx++;


The non-null check 'if (p_tr)' seem suspect, should it be 'if (p_pl)' 
instead since p_pl is being assigned (this maybe a cut-n-paste issue 
from a previous hunk of code that does:

                         op_idx++;
                         if (p_tr) {
                                 p_tr[tr_idx].set_number = tr_set_num;
                                 tr_set_num = 1 - tr_set_num;
                         }
                         tr_idx++;

Also, if it is meant to be a check on p_pl then surely the assignments 
to p_pl[] also need a non-null check in the cascaded if/else checks too.
