drivers: bus: Match against id_table first ...

Matching against driver's name before looking throught its id_table
can lead to a somewhat strange and unintuitive behaviour where a
device whose driver's name matches one of the lines in id_table (which
is not unheard of in Linux kernel) will be probed against said driver
with 'id_table' field set to NULL which in turn will result in
dev_get_drvdata erroring out with -ENODEV.

This patch changes the behaviour such that device_match() only tries
to match against driver's name only if id_table of that driver is not
present.

eeprom: Add support for 24c1025 EEPROM ...

This is the Microchip version of the Atmel 24c1024, which is already
supported.  The key difference between them is that the I2C address
bit used to select between the two banks is bit 2 for the 1025 and not
bit 0 as in the 1024.

Add a flag to describe this difference.

ARM: Fix bug in remap_range ...

remap_range takes generic MAP_CACHED/MAP_UNCACHED flags which are then
translated into the corresponding ARM specific bits. We call remap_range
internally from dma_alloc_* aswell, but instead of passing the generic
flags we pass the ARM specific bits.
Fix this by creating an internal __remap_range function which takes the
ARM specific bits and use it where appropriate.

usb: mx25: fix bit position of "Host power mask" ...

The bit MX25_H1_PM_BIT value is handled for port 1 as MX25_OTG_PM_BIT is
for port 0. The latter is called "OPM: OTG power mask" in the i.MX25
reference manual. Its description matches the description of "HPM: Host
power mask" for the host port which is bit 16, not 8.

The Linux kernel (as of 4.3) also has

	#define MX25_H1_PM_BIT                  BIT(16)

.

fs: smhfs: Fix return value of truncate() ...

Returning -ENOSYS as a result of truncate() breaks ability to write to
semihosting host's filesystem, so change the return value to 0. This
shouldn't cause any problems since all of the funcionlaity of
truncate() should is already handled by 'open' (via O_TRUNC) and
'write' (will automatically grow the file size when writing)
automatically

Unfortunately this was missed in original commit that introduced

edit: handle write() call errors in save_file() ...

save_file() did ignore possible errors of its write() calls.
Now the error code is used as return code for save_file().

write_full() is used instead of write() as it does not perform partial
writes which would require to check for returned size, too.
