Subject: [PATCH AUTOSEL 5.15 38/42] scsi: ufs: core: Fix missing clk change notification on host reset
Date: Tue, 19 Jul 2022 21:13:46 -0400	[thread overview]
Message-ID: <20220720011350.1024134-38-sashal@kernel.org> (raw)
In-Reply-To: <20220720011350.1024134-1-sashal@kernel.org>

From: Po-Wen Kao <powen.kao@mediatek.com>

[ Upstream commit 52a518019ca187227b786f8b8ee20869a97f3af4 ]

In ufshcd_host_reset_and_restore(), ufshcd_set_clk_freq() is called to
scale clock rate. However, this did not call vops->clk_scale_notify() to
inform platform driver of clock change.

Call ufshcd_scale_clks() instead so that clock change can be properly
handled.
