Subject: [PATCH 12/16] Replace for_each_*_bit_from() with for_each_*_bit() where appropriate
Date: Mon,  4 Oct 2021 22:40:55 -0700	[thread overview]
Message-ID: <20211005054059.475634-13-yury.norov@gmail.com> (raw)
In-Reply-To: <20211005054059.475634-1-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.
