The succ var tracks memory allocation erros on this function.

Fix it, in order to stop this W=1 Werror in clang:

drivers/staging/media/atomisp/pci/sh_css_params.c:2430:7: error: variable 'succ' set but not used [-Werror,-Wunused-but-set-variable]
        bool succ = true;
             ^

To mailbombing on a large number of people, only mailing lists were C/C on the cover.
See [PATCH 0/3] at: https://lore.kernel.org/all/cover.1636672052.git.mchehab+huawei@kernel.org/

Better to "return 0;"
