[PATCH 5.10 0/1] vdec_vp9_if: add check for NULL for vsi->frm_bufs[vsi->new_fb_idx].buf.fb in vp9_swap_frm_bufs

[Anastasia Belova]

Null-pointer dereference was found with static analysis tools 
in version 5.10. Seems this file doesn't exist since 5.18.
This file was moved to 
    /drivers/media/platform/mediatek/vcodec/vdec/vdec_vp9_if.c.
Maybe it is necessary to create another patch for these updates.
