There are only two requests for uac2, it may not be enough at high
loading system which usb interrupt handler can't be serviced on
time, then the data will be lost since it is isoc transfer for audio.
In this patch, we introduce a parameter for the number for usb request,
and the user can override it if current number for request is not enough
for his/her use case.
Besides, update this parameter for legacy audio gadget and documentation.

This commmit is the result of running checkpatch --fix.
The results were verified for correctness. Some of the fixes result in
line over 80 char which we will fix manually later.
The following is a summary of what was done by checkpatch:
* Remove externs on function prototypes.
* Replace symbolic permissions with octal.
* Align code to open parens.
* Replace 'unsigned' with 'unsigned int'.
* Remove unneccessary blank lines.
* Add blank lines after declarations.
* Add spaces around operators.
* Remove unnecessary spaces after casts.
* Replace 'x == NULL' with '!x'.
* Replace kzalloc() with kcalloc().
* Concatenate multi-line strings.
* Use the BIT() macro.

As IN request has to be allocated in set_alt() and released in
disable() we cannot use mutex to protect it as we cannot sleep
in those funcitons. Let's replace this mutex with a spinlock.

When we unlock our spinlock to copy data to user we may get
disabled by USB host and free the whole list of completed out
requests including the one from which we are copying the data
to user memory.
To prevent from this let's remove our working element from
the list and place it back only if there is sth left when we
finish with it.

When handing the SETUP packet by composite_setup(), we will release the
dwc->lock. If we get the 'USB_GADGET_DELAYED_STATUS' result from setup
function, which means we need to delay handling the STATUS phase.
But during the lock release period, maybe the request for handling delay
STATUS phase has been queued into list before we set 'dwc->delayed_status'
flag or entering 'EP0_STATUS_PHASE' phase, then we will miss the chance
to handle the STATUS phase. Thus we should check if the request for delay
STATUS phase has been enqueued when entering 'EP0_STATUS_PHASE' phase in
dwc3_ep0_xfernotready(), if so, we should handle it.

This new internal function will be used to solve a minor issue with dwc3
which exists in regards to short packets with OUT endpoints. Currently
we're asking gadget driver to *always* send us aligned requests; however
if we have enough TRBs we can easily append one extra TRB chained to the
previous and keep a throw away 1024 byte buffer around for that.
The actual fix will come in a separate patch, this is merely in
preparation for such fix.

We are already passing struct dwc3_request * to dwc3_prepare_one_trb(),
because of that there's no need to extract dma address and length in the
caller. We can let dwc3_prepare_one_trb() itself handle that part.
This simplifies the prototype of the function by removing two arguments.

Commit 05ee799f2021 ("usb: dwc2: Move gadget settings into core_params")
changes to type u16 for DT binding "g-rx-fifo-size" and
"g-np-tx-fifo-size" but use type u32 for "g-tx-fifo-size". Finally the
the first two parameters cannot be passed successfully with wrong data
format. This is found the data transferring broken on 96boards Hikey.
This patch is to change all parameters to u32 type, and verified on
Hikey board the DT parameters can pass successfully.

Since:
commit 855ed04a3758 ("usb: gadget: udc-core: independent registration
of gadgets and gadget drivers")
if we load gadget module but there is no free udc available
then it will be stored on a pending gadgets list.
$ modprobe g_zero.ko
$ modprobe g_ether.ko
[] udc-core: couldn't find an available UDC - added [g_ether] to list
of pending drivers
We scan this list each time when new UDC appears in system.
But we can get a free UDC each time after gadget unbind.
This commit add scanning of that list directly after unbinding
gadget from udc.
Thanks to this, when we unload first gadget:
$ rmmod g_zero.ko
gadget which is pending is automatically
attached to that UDC (if name matches).

The compacted-format XSAVES area is determined at boot time and
never changed after. The field xsave.header.xcomp_bv indicates
which components are in the fixed XSAVES format.
In fpstate_init() we did not set xcomp_bv to reflect the XSAVES
format since at the time there is no valid data.
However, after we do copy_init_fpstate_to_fpregs() in fpu__clear(),
as in commit:
b22cbe404a9c x86/fpu: Fix invalid FPU ptrace state after execve()
and when __fpu_restore_sig() does fpu__restore() for a COMPAT-mode
app, a #GP occurs. This can be easily triggered by doing valgrind on
a COMPAT-mode "Hello World," as reported by Joakim Tjernlund and
others:
https://bugzilla.kernel.org/show_bug.cgi?id=190061
Fix it by setting xcomp_bv correctly.
This patch also moves the xcomp_bv initialization to the proper
place, which was in copyin_to_xsaves() as of:
4c833368f0bf x86/fpu: Set the xcomp_bv when we fake up a XSAVES area
which fixed the bug too, but it's more efficient and cleaner to
initialize things once per boot, not for every signal handling
operation.

prom_init.c calls 'instance-to-package' twice, but the return
is not checked during prom_find_boot_cpu(). The result is then
passed to prom_getprop(), which could be PROM_ERROR. Add a return check
to prevent this.
This was found on a pasemi system, where CFE doesn't have a working
'instance-to package' prom call.
Before Commit 5c0484e25ec0 ('powerpc: Endian safe trampoline') the area
around addr 0 was mostly 0's and this doesn't cause a problem. Once the
macro 'FIXUP_ENDIAN' has been added to head_64.S, the low memory area
now has non-zero values, which cause the prom_getprop() call
to hang.
mpe: Also confirmed that under SLOF if 'instance-to-package' did fail
with PROM_ERROR we would crash in SLOF. So the bug is not specific to
CFE, it's just that other open firmwares don't trigger it because they
have a working 'instance-to-package'.

Currently, if the user add a stateful object with the name size exceed
NFT_OBJ_MAXNAMELEN - 1 (i.e. 31), we truncate it down to 31 silently.
This is not friendly, furthermore, this will cause duplicated stateful
objects when the first 31 characters of the name is same. So limit the
stateful object's name size to NFT_OBJ_MAXNAMELEN - 1.
