Before writing new PHY firmware to on-chip memory, driver queries
firmware for current running PHY firmware version, which can result
in sleep waiting for reply. So, move spinlock closer to the actual
on-chip memory write operation, instead of taking it at the callers.
Fixes: 5fff701c83 ("cxgb4: always sync access when flashing PHY firmware")

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.
