Subject: [PATCH v4 2/7] OPP: Move refcount and key update for readability in _opp_table_find_key()
Date: Wed, 20 Aug 2025 13:58:48 +0530 [thread overview]
Message-ID: <20250820-opp_pcie-v4-2-273b8944eed0@oss.qualcomm.com> (raw)
In-Reply-To: <20250820-opp_pcie-v4-0-273b8944eed0@oss.qualcomm.com>
Refactor _opp_table_find_key() to improve readability by moving the
reference count increment and key update inside the match condition block.
Also make the 'assert' check mandatory instead of treating it as optional.
