Subject: [PATCH] scsi: ufs: Give clk scaling min gear a value
Date: Wed, 27 Jan 2021 18:42:42 -0800	[thread overview]
Message-ID: <1611801769-20561-1-git-send-email-cang@codeaurora.org> (raw)

The initialization of clk_scaling.min_gear by mistake. This change adds it
back, otherwise clock scaling down would fail.

Fixes: 4543d9d78227 ("scsi: ufs: Refactor ufshcd_init/exit_clk_scaling/gating()")
