From: Kees Cook Date: Fri, 15 Nov 2019 05:07:13 +0000 (-0800) Subject: bnx2x: Remove config_init_t function casts X-Git-Tag: v5.15~5092^2~82^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3e19d1f2654ffd0e379c0f4ba30424bb57ed8acc;p=platform%2Fkernel%2Flinux-starfive.git bnx2x: Remove config_init_t function casts No callers of .config_init check return values. Remove the casting and change all callbacks to have the correct function prototype. Signed-off-by: Kees Cook Signed-off-by: David S.
