[ Upstream commit a37980ac5be29b83da67bf7d571c6bd9f90f8e45 ] v4l2-compliance fails with this message: warn: v4l2-test-formats.cpp(717): \ TRY_FMT cannot handle an invalid pixelformat. test VIDIOC_TRY_FMT: FAIL This causes the following kernel panic: Unable to handle kernel paging request at virtual address 56595561 pgd = ecd80e00 *pgd=00000000 Internal error: Oops: 205 [#1] PREEMPT SMP ARM ... CPU: 0 PID: 930 Comm: v4l2-compliance Not tainted \ 4.14.62-01715-gc8cd67f49a19 #1 Hardware name: Generic DRA72X (Flattened Device Tree) task: ece44d80 task.stack: ecc6e000 PC is at __vpe_try_fmt+0x18c/0x2a8 [ti_vpe] LR is at 0x8 Because the driver fails to properly check the 'num_planes' values for proper ranges it ends up accessing out of bound data causing the kernel panic. Since this driver only handle single or dual plane pixel format, make sure the provided value does not exceed 2 planes.
