[PATCH 11/24] Staging: atomisp: fix an uninitialized variable bug

[Alan Cox]

From: Dan Carpenter <dan.carpen...@oracle.com>

There are some error paths in atomisp_css_frame_allocate() which don't
initialize "res" so it could lead us to try release random memory.

Fixes: a49d25364dfb ("staging/atomisp: Add support for the Intel IPU v2")
