Subject: [PATCH AUTOSEL 5.4 2/7] mmc: core: Respect quirk_max_rate for non-UHS SDIO card
Date: Sun, 26 Jan 2025 10:05:22 -0500 [thread overview]
Message-ID: <20250126150527.960265-2-sashal@kernel.org> (raw)
In-Reply-To: <20250126150527.960265-1-sashal@kernel.org>
From: Shawn Lin <shawn.lin@rock-chips.com>
[ Upstream commit a2a44f8da29352f76c99c6904ee652911b8dc7dd ]
The card-quirk was added to limit the clock-rate for a card with UHS-mode
support, although let's respect the quirk for non-UHS mode too, to make the
behaviour consistent.
