[ Upstream commitee8c88cab4] Fix the following issues in ufshcd_poll(): - If polling succeeds, return a positive value. - Do not complete polling requests from interrupt context because the block layer expects these requests to be completed from thread context. From block/bio.c: If REQ_ALLOC_CACHE is set, the final put of the bio MUST be done from process context, not hard/soft IRQ.

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.
