As warned by gcc 12.1: drivers/staging/media/atomisp/pci/runtime/rmgr/src/rmgr_vbuf.c: In function 'ia_css_rmgr_acq_vbuf': drivers/staging/media/atomisp/pci/runtime/rmgr/src/rmgr_vbuf.c:275:33: error: storing the address of local variable 'h' in '*handle' [-Werror=dangling-pointer=] 275 | *handle = &h; | ~~~~~~~~^~~~ drivers/staging/media/atomisp/pci/runtime/rmgr/src/rmgr_vbuf.c:257:40: note: 'h' declared here 257 | struct ia_css_rmgr_vbuf_handle h; | ^ drivers/staging/media/atomisp/pci/runtime/rmgr/src/rmgr_vbuf.c:257:40: note: 'handle' declared here cc1: all warnings being treated as errors The logic uses a temporary struct to update the handler, but, instead of copying the value to the pointer sent by the caller, it replaces it with the content with a local variable. That's wrong, and may lead the caller to use a weird value. Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
