[PATCH 1/1] scsi: ufs: fix missing clk change notification on host reset

From: Po-Wen Kao
Date: Mon Jul 11 2022 - 10:43:09 EST


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

We propose to call on ufshcd_scale_clks() instead so that clk change
can be properly handled.
