7b1425f08f pinctrl: renesas: Protect GPIO leftovers by CONFIG_PINCTRL_SH_FUNC_GPIO
On SuperH and ARM SH/R-Mobile SoCs, the pin control driver handles
GPIOs, too.  To reduce code size when compiling a kernel supporting only
modern SoCs, most, but not all, of the GPIO functionality is protected
by checks for CONFIG_PINCTRL_SH_FUNC_GPIO.

Factor out the remaining parts when not needed:
  1. sh_pfc_soc_info.{in,out}put describe GPIO pins that have input
     resp. output capabilities (SuperH and SH/R-Mobile).
  2. sh_pfc_soc_info.gpio_irq{,_size} describe the mapping from GPIO
     pins to interrupt numbers (SH/R-Mobile).
  3. sh_pfc_gpio_set_direction() configures GPIO direction, called from
     the GPIO driver through pinctrl_gpio_direction_{in,out}put()
     (SH/R-Mobile).  Unfortunately this function cannot just be moved to
     drivers/pinctrl/renesas/gpio.c, as it relies on knowledge of
     sh_pfc_pinctrl, which is internal to
     drivers/pinctrl/renesas/pinctrl.c.

While code size reduction is minimal, this does help in documenting
depencies.

a3ee0a246d pinctrl: renesas: r8a7778: Use common R-Car bias handling
Currently, the rcar_pinmux_[gs]et_bias() helpers handle only SoCs that
have separate LSI Pin Pull-Enable (PUEN) and Pull-Up/Down Control (PUD)
registers, like R-Car Gen3 and RZ/G2.  Update the function to handle
SoCs that have only LSI Pin Pull-Up Control Register (PUPR), like R-Car
Gen1/Gen2 and RZ/G1.

Reduce code duplication by converting the R-Car M1A pin control driver
to use the common handler.

Note that this changes behavior in case the (invalid!) option
"bias-pull-down" is used in an R-Car M1A DTS: before, it was ignored
silently; after this change, it is considered the same as
"bias-pull-up".

2d341cc3da pinctrl: renesas: r8a7778: Use physical addresses for PUPR regs
The handling of the LSI Pin Pull-Up Control Registers (PUPR) on R-Car
M1A uses register offsets instead of register physical addresses.
This is different from the handling on other R-Car parts.

Convert the bias handling from register offsets to physical addresses.
This increases uniformity, and prepares for consolidation of the bias
handling.

8019938a85 pinctrl: renesas: Optimize sh_pfc_pin_config
Shrink sh_pfc_pin_config from 8 to 2 bytes:
  - The mux_set flag can be removed, as a non-zero mark value means the
    same (zero = PINMUX_RESERVED is an invalid mark value),
  - The gpio_enabled flag needs only a single bit,
  - Mark values are small integers, and can easily fit in a 15-bit
    bitfield.

This saves 6 bytes per pin when allocating the sh_pfc_pinctrl.configs
array, i.e. it reduces run-time memory consumption by ca. 1.5 KiB.

eb9d673f94 pinctrl: renesas: Reorder struct sh_pfc_pin to remove hole
On arm64, pointer size and alignment is 64-bit, hence a 4-byte hole is
present in between the enum_id and name members of the sh_pfc_pin
structure.  Get rid of this hole by sorting the structure's members by
decreasing size.

This saves up to 1.5 KiB per enabled SoC, and reduces the size of a
kernel including support for all R-Car Gen3 SoCs by more than 10 KiB.

This has no size impact on SH and arm32.

6a6516c024 USB: storage: avoid use of uninitialized values in error path
When usb_stor_bulk_transfer_sglist() returns with USB_STOR_XFER_ERROR, it
returns without writing to its parameter *act_len.

Further, the two callers of usb_stor_bulk_transfer_sglist():

    usb_stor_bulk_srb() and
    usb_stor_bulk_transfer_sg(),

use the passed variable partial without checking the return value. Hence,
the uninitialized value of partial is then used in the further execution
of those two functions.

Clang-analyzer detects this potential control and data flow and warns:

  drivers/usb/storage/transport.c:469:40:
    warning: The right operand of '-' is a garbage value
    [clang-analyzer-core.UndefinedBinaryOperatorResult]
          scsi_set_resid(srb, scsi_bufflen(srb) - partial);
                                                ^

  drivers/usb/storage/transport.c:495:15:
    warning: Assigned value is garbage or undefined
    [clang-analyzer-core.uninitialized.Assign]
                  length_left -= partial;
                              ^

When a transfer error occurs, the *act_len value is probably ignored by the
higher layers. But it won't hurt to set it to a valid number, just in case.

For the two early-return paths in usb_stor_bulk_transfer_sglist(), the
amount of data transferred is 0.  So if act_len is not NULL, set *act_len
to 0 in those paths. That makes clang-analyzer happy.

Proposal was discussed in this mail thread:

regulator: workaround self-referent regulators
Workaround regulators whose supply name happens to be the same as its
own name. This fixes boards that used to work before the early supply
resolving was removed. The error message is left in place so that
offending drivers can be detected.

8d0dd23c6c syscalls: Fix file comments for syscalls implemented in kernel/sys.c
The relevant syscalls were previously moved from kernel/timer.c to kernel/sys.c,
but the comments weren't updated to reflect this change.

Fixing these comments messes up the alphabetical ordering of syscalls by
filename. This could be fixed by merging the two groups of kernel/sys.c syscalls,
but that would require reordering the syscalls and renumbering them to maintain
the numerical order in unistd.h.

76255470ff xhci: hisilicon: fix refercence leak in xhci_histb_probe
pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. We should decrease the usage count
whetever it succeeded or failed(maybe runtime of the device has
error, or device is in inaccessible state, or other error state).
If we do not call put operation to decrease the reference, it will
result in reference leak in xhci_histb_probe. Moreover, this
device cannot enter the idle state and always stay busy or other
non-idle state later. So we fixed it by jumping to error handling
branch.

ffa13d2d94 Revert "usb: musb: convert to devm_platform_ioremap_resource_byname"
This reverts commit 2d30e408a2.

On Beaglebone Black, where each interface has 2 children:

    musb-dsps 47401c00.usb: can't request region for resource [mem 0x47401800-0x474019ff]
    musb-hdrc musb-hdrc.1: musb_init_controller failed with status -16
    musb-hdrc: probe of musb-hdrc.1 failed with error -16
    musb-dsps 47401400.usb: can't request region for resource [mem 0x47401000-0x474011ff]
    musb-hdrc musb-hdrc.0: musb_init_controller failed with status -16
    musb-hdrc: probe of musb-hdrc.0 failed with error -16

Before, devm_ioremap_resource() was called on "dev" ("musb-hdrc.0" or
"musb-hdrc.1"), after it is called on "&pdev->dev" ("47401400.usb" or
"47401c00.usb"), leading to a duplicate region request, which fails.

53bf2776e3 ARM: dts: exynos: revert "add input clock to CMU in Exynos4412 Odroid"
This reverts commit eaf2d2f689.

The commit eaf2d2f689 ("ARM: dts: exynos: add input clock to CMU in
Exynos4412 Odroid") breaks probing of usb3503 USB hub on Odroid U3.

It changes the order of clock drivers probe: the clkout (Exynos PMU)
driver is probed before the main clk-exynos4 driver.  The clkout driver
on Exynos4412 depends on clk-exynos4 but it does not support deferred
probe, therefore this dependency and changed probe order causes probe
failure.

The usb3503 USB hub on Odroid U3 on the other hand requires clkout
clock.  This can be seen in logs:

    [    5.007442] usb3503 0-0008: unable to request refclk (-517)
