5.15-stable review patch. If anyone has any objections, please let me know.

commit 8403fdd775858a7bf04868d43daea0acbe49ddfc upstream.
The venus_helper_alloc_dpb_bufs() implementation allows an early return on an error path when checking the id from ida_alloc_min() which would not release the earlier buffer allocation.
Move the direct kfree() from the error checking of dma_alloc_attrs() to the common fail path to ensure that allocations are released on all error paths in this function.
Addresses-Coverity: 1494120 ("Resource leak")
