[ Upstream commit2d93887cb4] Since commit0d58280cf1("phy: Update PHY power control sequence") the PHY is powered on before configuring the registers and only the MSM8996 PCIe PHY, which includes the POWER_DOWN_CONTROL register in its PCS initialisation table, may possibly require a second update afterwards. To make things worse, the POWER_DOWN_CONTROL register lies at a different offset on more recent SoCs so that the second update, which still used a hard-coded offset, would write to an unrelated register (e.g. a revision-id register on SC8280XP). As the MSM8996 PCIe PHY is now handled by a separate driver, simply drop the bogus register update.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
