Thanks Ashish
>From 770317157c3a7abf2fda1d71b0bd651c33bf0bfa Mon Sep 17 00:00:00 2001 From: Ashish Kalra <eashishka...@gmail.com> Date: Sun, 18 Apr 2021 06:52:03 +0530 Subject: [PATCH] media: atomisp: silence "dubious: !x | !y" warning Upon running sparse, "warning: dubious: !x | !y" is brought to notice for this file. Logical and bitwise OR are basically the same in this context so it doesn't cause a runtime bug. But let's change it to logical OR to make it cleaner and silence the Sparse warning.
