[media] cx24120: Add missing command to cx24120_check_cmd
This patch adds in a missing command to cx24120_check_cmd. This part
of the old reverse engineered driver was quite hard to follow - it's
presumed the compiler did some neat optimisation that wasn't easy to
decode. This command was checked for in that version but not copied
across to the new switch statement.
For reference, old reverse engineered code:
xxzz = cmd->id - 0x11; // look for specific message id
if ( xxzz <= 0x13 ) {
msg_cmd_mask = 1 << xxzz;
//0x0F8021 // if cmd_id 17 or 22 or 33-36, 42, 47, 57-61 etc. disable mpeg output
if ( msg_cmd_mask & 0x0F8021 ) { // 000011111000000000100001b
cx24120_msg_mpeg_output_global_config(state, 0);
msleep(100);
state->dvb_s2_mode &= 0xFD; // reset mpeg out enable flag
}
}
