[PATCH AUTOSEL 5.10 23/25] scsi: ufs: core: Fix missing clk change notification on host reset

[Sasha Levin]

From: Po-Wen Kao <powen.kao at 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.
