Commit2760878662("clk: Bail out when calculating phase fails during clk registration") introduced a check on error values at the time the clock is registered to bail out when such an error occurs. However, it doesn't check whether the returned value is positive which will happen if the driver returns a non-zero phase. Since a phase is usually a non-zero positive number this ends up returning something that isn't 0 to the caller of __clk_core_init(), making most clks fail to register if they implement a phase clk op and return anything besides 0 for the phase. Fix this by returning the error if phase is less than zero or just return zero if the phase is a positive number.

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.
