[ Upstream commit 58043dbf6d1ae9deab4f5aa1e039c70112017682 ]
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; ^
