[ Upstream commit bd6781c18cb5b5e5d8c5873fa9a51668e89ec76e ]
The wait_event_interruptible_timeout() function returns 0
if the timeout elapsed, -ERESTARTSYS if it was interrupted
by a signal, and the remaining jiffies otherwise if the
condition evaluated to true before the timeout elapsed.
Driver should have checked for zero return value instead of
a positive value.
MChan: Print a warning for -ERESTARTSYS. The close operation
will proceed anyway when wait_event_interruptible_timeout()
returns for any reason. Since we do the close no matter what,
we should not return this error code to the caller. Change
bnxt_close_nic() to a void function and remove all error
handling from some of the callers.
Fixes: c0c050c58d ("bnxt_en: New Broadcom ethernet driver.")

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.
