Commitcc7ad0d77b("drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback()") besides fixing the deadlock also modified rtw_scan_timeout_handler() to use spin_[un]lock_irq() instead of spin_[un]lock_bh(). Disabling the IRQs is not necessary since all code taking this lock runs from either user contexts or from softirqs rtw_scan_timeout_handler() is the only function taking pmlmepriv->lock which uses spin_[un]lock_irq() for this. Switch back to spin_[un]lock_bh() to make it consistent with the rest of the code.

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.
