[PATCH v3 0/2] Fixes for UFS clock gating initialization

From: Avri Altman

Martin hi,

This patch series addresses two issues related to the UFS clock gating
mechanism. The first patch ensures that the `clk_gating.lock` is used
only after it has been properly initialized.

The second patch fixes an issue where `clk_gating.state` is toggled even
if clock gating is not allowed, which can lead to crashes.

Changes since v2:
- Add patch #2 (Geert)
- Initialize clk_gating.lock unconditionally (Bart)

Changes since v1:
- move the spin_lock_init(&hba->clk_gating.lock) call from
ufshcd_init_clk_gating() just before the ufshcd_hba_init() call in
ufshcd_init() (Bart)

Avri Altman (2):
scsi: ufs: core: Ensure clk_gating.lock is used only after
initialization
scsi: ufs: Fix toggling of clk_gating.state when clock gating is not
allowed
