Subject: [PATCH 12/16] Replace for_each_*_bit_from() with for_each_*_bit() where appropriate
Date: Fri, 1 Oct 2021 11:12:41 -0700 [thread overview]
Message-ID: <20211001181245.228419-13-yury.norov@gmail.com> (raw)
In-Reply-To: <20211001181245.228419-1-yury.norov@gmail.com>
A couple of kernel functions call for_each_*_bit_from() with start
bit equal to 0. Replace them with for_each_*_bit().
No functional changes, but might improve on readability.
