Subject: [PATCH v3 11/35] ath10k: optimize ath10k_snoc_napi_poll()
Date: Mon, 11 Dec 2023 18:27:25 -0800 [thread overview]
Message-ID: <20231212022749.625238-12-yury.norov@gmail.com> (raw)
In-Reply-To: <20231212022749.625238-1-yury.norov@gmail.com>
ath10k_snoc_napi_poll() traverses pending_ce_irqs bitmap bit by bit.
Simplify it by using for_each_test_and_clear_bit() iterator.
