Currently if the allocation of new_buf fails then a null pointer
|
|
dereference occurs when assiging new_buf->vb. Avoid this by returning
|
|
early on a memory allocation failure as there is not much more can
|
|
be done at this point.
|
|
|
|
Addresses-Coverity: ("Dereference null return")
|
|
Fixes: 3e7f51bd9607 ("media: meson: add v4l2 m2m video decoder driver")
