From: Chen-Yu Tsai <wens(a)csie.org>
When support for the R40 in the rtc-sun6i driver was split out for a
separate compatible string, only the RTC half was covered, and not the
clock half. Unfortunately this results in the whole driver not working,
as the RTC half expects the clock half to have been initialized.
Add support for the clock part as well. The clock part is like the H3,
but does not need to export the internal oscillator, nor does it have
a gateable LOSC external output.
This fixes issues with WiFi and Bluetooth not working on the BPI M2U.

This is a note to let you know that I've just added the patch titled
staging: rtl8188eu: fix interface sanity check
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: staging: rtl8188eu: fix interface sanity check
Make sure to use the current alternate setting when verifying the
interface descriptors to avoid binding to an invalid interface.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.
