This patch fixes improper in_pressure_scale output that is
returned by the lps331ap barometer sensor driver. According
to the documentation the pressure after applying the scale has to
be expressed in kilopascal units. With erroneous implementation
the scale value larger by two orders of magnitude is returned -
2441410 instead of 24414.

The removed check in the read_raw implementation was always true,
therefore remove it. This also fixes a bug, by closely inspecting
the code, one can notice the iio_validate_scan_mask_onehot() will
always return 1 and therefore the subsequent condition will always
succeed, therefore making the mxs_lradc_read_raw() function always
return -EINVAL; .

The struct iio_dev .trig field is to be used only by the IIO core,
the driver shall not fill this field. This fixes ugly crash when
the driver is compiled as a module and the module is rmmod'd.

When reading IIO_CHAN_INFO_OFFSET, the return value of iio_channel_read() for
success will be IIO_VAL*, checking for 0 is not correct.
Without this fix the offset applied by iio drivers will be ignored when
converting a raw value to one in appropriate base units (e.g mV) in
a IIO client drivers that use iio_convert_raw_to_processed including
iio-hwmon.

Since the info_mask split, iio_channel_has_info() is not working correctly.
info_mask_separate and info_mask_shared_by_type, it is not possible to compare
them directly with the iio_chan_info_enum enum. Correct that bit using the BIT()
macro.

This reverts commit ee04fd11f11fb67ff0ae482a6710f97f499c19e2.
How many times can we do this...
Not all the world is x86-64, breaking other arch builds, especially for
weeks at a time, isn't acceptable at all.
So, it's nice to get this code into the tree, just don't build it as
it's obviously not ready for "real world" systems :(

During the attach of this driver, it's possible for the allocation

This patch fixes the following checkpatch warning:
WARNING: msleep < 20ms can sleep for up to 20ms
The implementation of msleep() is based on jiffies timeout
subsystem. Hence, its resolution is constrained by the value
of HZ tick rate. When HZ variable is configured to 100,
the jiffies variable is updated every 10 ms, so a timeout
of 1ms cannot be met using jiffies (it will be rounded up
to 10ms).
This patch replaces msleep(1) with usleep_range(1000, 1000).
usleep_range() uses hrtimers subsystem which is not bound
to HZ value and can provide microsecond-level resolution.

This patch renames the following variables:
'dwRegRead' into 'reg'
'rtStatus' into 'status'
This is done primarily to reduce line length below 80 chars,
since the size and the usage of dwRegRead variable
can be deduced by its type and the function called
to assign it, so it can be replaced by simply 'reg'.
Also, rtStatus is not more informative than just status
in the given context.

This patch limits the line size below 80 characters,
when possible without producing new checkpatch errors.
This is done by adjusting identation, replacing hardcoded
function names in messages with __func__, merging some
trailing comments with the header comments when they both
refer to the same line and removing some unnecessary
parenthesis.
Also, changes slightly some RT_TRACE messages to make
them shorter without altering their content.

Move zram sysfs code to zram drv and remove zram_sysfs.c
file. This gives ability to make static a number of previously
exported zram functions, used from zram sysfs, e.g. internal zram
zram_meta_alloc/free(). We also can drop zram_drv wrapper

e.g. zram_reset_device()/__zram_reset_device() pair.

The SCmdLinkStatus struct has a couple holes. There is one between
->bLink and ->wBSSType, and another between ->abySSID and ->uChannel.
I've added a memset() to initialize the struct to zero. Since we don't
need to clear abySSID any more so I've removed that memset. It was
wrong anyway: abySSID has "SSID_MAXLEN + 2" (34) bytes, not
"WLAN_SSID_MAXLEN + 1" (33).

I screwed up the sense of this if() statement while porting our
vendor driver to create the dwc2 driver. This caused frame overrun
errors on periodic transfers when there were other transfers
active in the same (micro)frame.
With this fix, the dwc2 driver now works on the Raspberry Pi
platform even with the USB Ethernet controller enabled, where
before that would cause all USB devices to stop working.
Thanks to Ray Jui and Jerry Lin at Broadcom for tracking this down.

__sync_fetch_and_and and __sync_fetch_and_or are functions that are provided
by gcc and depending on the target architecture may be implemented in libgcc,
which is not always available in the kernel. This leads to a build failure
on ARMv5:
drivers/built-in.o: In function `line6_pcm_release':
:(.text+0x3bfe80): undefined reference to `__sync_fetch_and_and_4'
drivers/built-in.o: In function `line6_pcm_acquire':
:(.text+0x3bff30): undefined reference to `__sync_fetch_and_or_4'
To work around this, we can use the kernel-provided cmpxchg macro.
