Subject: [PATCH 1/6] sound: soc: codecs: da7219: convert from round_rate() to determine_rate()
Date: Thu, 10 Jul 2025 11:51:07 -0400	[thread overview]
Message-ID: <20250710-sound-clk-round-rate-v1-1-4a9c3bb6ff3a@redhat.com> (raw)
In-Reply-To: <20250710-sound-clk-round-rate-v1-0-4a9c3bb6ff3a@redhat.com>

The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
on the cover letter of this series.
