RE: [PATCH v2 3/6] phy: samsung: ufs: support secondary ufs phy

quoted

+	phy->isol = devm_kzalloc(dev, sizeof(struct pmu_isol), GFP_KERNEL);

1. Looks like devm_kmemdup
2. sizeof(*variable), not sizeof(struct)

3. and actually you can simplify all that by storing struct pmu_isol
directly in struct samsung_ufs_phy, not as pointer.

After all that storing drvdata in samsung_ufs_phy does not make any sense
- only one field is left still used (has_symbol_clk), so this should be
simplified here as well.

It would be better storing struct pmu_isol directly and remove drvdata from samsung_ufs_phy as you suggested.
Furthermore, definition of struct pmu_isol looks odd in the definition of samsung_ufs_phy_drvdata.
So, I'll pop it out and change the naming to "struct samsung_ufs_phy_pmu_isol"
