Subject: [PATCH 5/5] x86/unwind/orc: delete dead write in __orc_find()
Date: Fri, 11 Mar 2022 17:43:12 +0300	[thread overview]
Message-ID: <20220311144312.88466-5-adobriyan@gmail.com> (raw)
In-Reply-To: <20220311144312.88466-1-adobriyan@gmail.com>

Also move "mid" variable to the innermost scope and delete useless
parenthesis while I'm at it.
