This patch series resolves a kernel-doc warning and a clk freeing bug
that was causing a crash.
This patch series is on top of:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/usb/dwc3?id=84770f028fabab4cb66188d583ed12652f30576b
Manish Narani (2):
usb: dwc3:
The kernel-doc run gave a warning for Xilinx DWC3 driver:
drivers/usb/dwc3/dwc3-xilinx.c:27: warning: expecting prototype for
dwc3(). Prototype was for XLNX_USB_PHY_RST_EN() instead
Basically it was due to an extra '*' in line:2. This patch fixes the same.
Signed-off-by: Manish Narani
The clocks are configured by devm_clk_bulk_get_all() in this driver. In
case of any error the clocks freeing will be handled automatically.
There is no need to explicitly free the clocks. Fix the same.

Declaring a static array in a header file is likely to cause name conflicts
if the declaration is pulled in multiple times.
The rtl8188 driver protects the declaration of the wlancmds array in
rtw_mlme_ext.h with ifdef _RTW_CMD_C_, which is defined only in rtw_cmd.c.
It makes more sense to
Move the declaration of the rtw_cmd_callback array from rtw_cmd.h to

The _RTW_CMD_C_ symbol is now obsolete and can be removed.

uses a label and goto instead of the actual loop. We only get back to the

Fixed multiple bare uses of 'unsigned' without 'int'.
Fixed space around "*" operator.
Fixed function parameter alignment to opening parenthesis.

When the unsigned page_counter underflows, even just by a few pages, a

Underflows shouldn't happen, but when they do in practice, we may just
be off by a small amount that doesn't

This should be WARN_ON_ONCE(!svm->ghcb), otherwise you'll get the right
result, but get a stack trace immediately.

do_each_pid_thread() { } while_each_pid_thread() is a double loop and
thus break doesn't work as expected. Also, it should be used under
tasklist_lock because otherwise we can race against change_pid() for
PGID/SID.

Do not include private headers and do not frob in internals.
On top of that, while the previous code restores the affinity, it
doesn't ensure the task actually moves there if it was running,
leading to the fun situation that it can be observed running outside

Given this is sprinkled all over the place, can you make this a
static_key_false + static_branch_unlikely() such that the hybrid case is
out-of-line?
All callers of pci_p2pdma_map_type() have a struct dev_pgmap and a
struct device (of the client doing the DMA transfer). Thus move the
conversion to struct pci_devs for the provider and client into this
function.

Attempt to find the mapping type for P2PDMA pages on the first
DMA map attempt if it has not been done ahead of time.
Previously, the mapping type was expected to be calculated ahead of
time, but if pages are to come from userspace then there's no
way to ensure the path was checked ahead of time.
