find_tlb_idx() is called in board_early_init_r() on multiple boards. The return value is not checked before being used to disable a TLB. In normal case the return value wouldn't be -1. In case of a mis- configuration during porting to a new board, checking the return value may be helpful to reveal some user errors. Signed-off-by: York Sun <yorksun@freescale.com>
