The driver calls mdelay(15) in the ->suspend, ->resume, ->runtime_suspend
and ->runtime_resume hook, however spinning for such a long period of
time is discouraged as per Documentation/timers/timers-howto.txt.
The use of mdelay() seems unnecessary, it is allowed to sleep in the
system sleep and runtime PM hooks (with the exception of ->suspend_noirq
and ->resume_noirq) and the driver itself also does not rely on a
non-sleeping ->runtime_resume as the only place where a synchronous
resume is performed, in bcm_dequeue(), is called from a work item in
hci_ldisc.c and hci_serdev.c.
So replace the mdelay(15) with msleep(15).
Note that the delay is inserted after asserting or deasserting the
device wake pin, but in bcm_gpio_set_power() that pin is asserted or
deasserted *without* observing a delay. It is thus unclear if the delay
is necessary at all. It is likewise unclear why it is exactly 15 ms,

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
