Creation of LUN 0 may fail (for example due to ENOMEM).
As fsg_common_set_num_buffers() does some memory allocation
we should free it before it becomes unavailable.

When a SoC supports both PHY interfaces but
doesn't define HSPHY in DT/pdata, we will get
an unnecessary dev_warn() which can mislead users
into thinking that they're missing something.
Instead, let's just silently rely on a correct
default. If the HW default is wrong, then HSPHY
is required and USB won't work, this will be
motivation enough for engineers to patch their
way into a working setup.

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Currently this parameter is made optional with the help of a cpp trick.
To allow dropping this hack convert callers to explictly pass a value
for flags.

which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Use this additional parameter and the _optional variant to simplify the
driver and improve error handling. Also expand the comment to explain
why it's not sensible to switch to devm_gpiod_get and why the gpiod_put
is also necessary.
Furthermore this is one caller less that stops us making the flags
argument to gpiod_get*() mandatory.

In big endian cases, the macro cpu_to_le{16,32} unfolds to __swab{16,32}
which provides special case for constants. In little endian cases,
__constant_cpu_to_le{16,32} and cpu_to_le{16,32} expand directly to
the same expression. So, replace __constant_cpu_to_le{16,32} with
cpu_to_le{16,32} with the goal of getting rid of the definition of
__constant_cpu_to_le{16,32} completely.
The semantic patch that performs this transformation is as follows:
@@expression x;@@
(
- __constant_cpu_to_le16(x)
+ cpu_to_le16(x)
|
- __constant_cpu_to_le32(x)

now that we have no users of dev_dbg() in dwc3,
we can safely remove CONFIG_USB_DWC3_DEBUG.
If dev_dbg() is ever strictly necessary - and I
don't see why it would, considering we want to
rely on tracepoints for debug - we will depend
on DYNAMIC_PRINTK to enable such messages.

A new BLK namespace "seed" device is created whenever the current seed
is successfully probed. However, if that namespace is assigned to a BTT
it may never directly experience a successful probe as it is a
subordinate device to a BTT configuration.
The effect of the current code is that no new namespaces can be
instantiated, after the seed namespace, to consume available BLK DPA
capacity. Fix this by treating a successful BTT probe event as a
successful probe event for the backing namespace.

Devices may declare more LEDs than what is known to input-leds
(HID does this for some devices). Instead of showing ugly warnings
on connect and, even worse, oopsing on disconnect, let's simply
ignore LEDs that are not known to us.

DMA transfers must be greater than the watermark level size. spi_imx->rx_wml
and spi_imx->tx_wml contain the watermark level in 32bit words whereas struct
spi_transfer contains the transfer len in bytes. Fix the check if DMA is
possible for a transfer accordingly. This fixes transfers with sizes between
33 and 128 bytes for which previously was claimed that DMA is possible.

pdev->dev.platform_data is not initialized if match is true in function
sdhci_pxav3_probe. Just local variable pdata is assigned the return value
from function pxav3_get_mmc_pdata().
