It does not make sense to write new value only when all the bit_mask

When SDIO runtime PM was originally introduced, we immediately faced
two regressions with two different chipsets, and in response decided
not to enable it by default.
With the recent work on the 8686 we hoped we found all the gotchas,
so 08da834 did make sense (at least experimentally).
Unfortunately we now see that some setups out there still refuse to
work when SDIO runtime PM is enabled by default (see
http://www.spinics.net/lists/linux-mmc/msg11161.html), and obviously
we can't live with these kind of regressions.
This reverts commit 08da834a24312157f512224691ad1fddd11c1073.

Since we configure all the queues as CHAINABLE, we need to update the

Not doing so can confuse the SCD and make the fw assert.

private_data_len is defined as a u8. If the user specifies a large
private_data size (> 220 bytes), we will calculate a total length that
exceeds 255, resulting in private_data_len wrapping back to 0. This
can lead to overwriting random kernel memory. Avoid this by verifying
that the resulting size fits into a u8.

If oprofilefs_ulong_from_user() is called with count equals
zero, *val remains unchanged. Depending on the implementation it
might be uninitialized.
Change oprofilefs_ulong_from_user()'s interface to return count
on success. Thus, we are able to return early if count equals
zero which avoids using *val uninitialized. Fixing all users of
oprofilefs_ulong_ from_user().
This follows write syscall implementation when count is zero:
"If count is zero ... [and if] no errors are detected, 0 will be
returned without causing any other effect." (man 2 write)

We should not change gadget driver's descriptors just
because we think it's right to do so.
There are several of reasons which would support this
statement but it suffices to say that this was probably
never tested because it updates bmAttributes without
asking the driver if it's ok to do so.
This means that e.g. on UASP gadget it would enable
stream support even for the command endpoint which must
not have stream support enabled.
In fact, this change is fixing the bug introduced by
commit a59d6b9 (usb: gadget: add streams support to
the gadget framework) which was caught when testing
UASP gadget with dwc3 driver.

I noticed that hotplug of one setup does not work with recent change in
pci tree.
After checking the bridge conf setup, I noticed that the bridges get
assigned but do not get enabled.
The reason is the following commit, while simply ignores bridge
resources when enabling a pci device:
| commit bbef98ab0f019f1b0c25c1acdf1683c68933d41b
| Author: Ram Pai <linuxram@us.ibm.com>
| Date: Sun Nov 6 10:33:10 2011 +0800
|
| PCI: defer enablement of SRIOV BARS
|...
| NOTE: Note, there is subtle change in the pci_enable_device() API. Any
| driver that depends on SRIOV BARS to be enabled in pci_enable_device()
| can fail.
Put back bridge resource and ROM resource checking to fix the problem.
That should fix regression like BIOS does not assign correct resource to
bridge.

Before registering an adapter to i2c subsystem, we need make sure
driver is ready for incoming i2c xfer, becasue the i2c_add_adapter()
may trigger a i2c device driver's proble function which may start
some real i2c xfer. I met this issue when integrating a TSC2007 i2c
touch screen device with the i2c-eg20t driver.
This patch will call request_irq() and hw init before calling
i2c_add_adapter().

s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined
in the platform data of the i2c device. When DT is not enabled,
the above function always returns -EINVAL. Since there can be
some i2c devices which don't need to configure any gpio lines,
the probe of such devices would fail here. Changing the default
return value to success would fix this issue.
