Subject: [PATCH v2 0/6] usb: phy: msm: Fixes and cleanups

From: "Ivan T. Ivanov" <[email protected]>

v2
--
* Fix compilation issue in patch 1
* Separate regulator changes
* Merge devm_ related changes to one commit
* Drop Lindent patch

v1
--
Following patches make initial cleanup of usb phy found in the Qualcomm
chipsets. Changes include:
* Build time error fix.
* Move driver to Managed Device Resource allocation.
* Checkpatch warnings and error fixes
* Removed usage of global regulators variables.

Ivan T. Ivanov (6):
usb: phy: msm: Move mach depndend code to platform data
usb: phy: msm: move global regulators variables to driver state
usb: phy: msm: Migrate to Managed Device Resource allocation
usb: phy: msm: Remove unnecessarily check for valid regulators.
usb: phy: msm: Fix WARNING: quoted string split across lines
usb: phy: msm: Fix WARNING: Prefer seq_puts to seq_printf

Subject: [PATCH v2 4/6] usb: phy: msm: Remove unnecessarily check for valid regulators.

From: "Ivan T. Ivanov" <[email protected]>

Whether regulators are available or not is checked at driver
probe. If they are not available driver will refuse to load,
so no need to check them again.
