From 2c855d73f2f6107f5b8ebc45f8b934bf7f4419e0 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 14 Nov 2019 21:07:12 -0800 Subject: [PATCH] bnx2x: Remove read_status_t function casts The function casts for .read_status callbacks end up casting some int return values to u8. This seems to be bug-prone (-EINVAL being returned into something that appears to be true/false), but fixing the function prototypes doesn't change the existing behavior. Fix the return values to remove the casts. Signed-off-by: Kees Cook Signed-off-by: David S.
