ae2b48e84a doc: allow building htmldoc with Sphinx 3+
Due to removed function c_funcptr_sig_re building with Sphinx 3 fails.

With the patch building succeeds with a lot of warnings if the '-W' flag is
removed from doc/Makefile. Most of the documentation is correct

This follows the approach taken by the Linux kernel.

5c88b6ad40 usb: dwc3-meson-g12a: always configure dr-mode
dwc3_meson_g12a_force_mode() sets the dr-mode of the USB PHY. However
it skips setting the mode if it matches the one done during driver probe
(stored in private structure). This fails if the mode has been changed
to other value and then back to initial one. Fix this by configuring the
dr-mode always, regadless of the one set at the driver probe).

This fixes operation of USB gadget based drivers when they are initialized
for the second time.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
