I2C-controlled MEMS sensor with 20-bit pressure measurement (pascal) and
12-bit temperature measurement

driver only exposes basic functionality, see TODO remarks
datasheet: http://cache.freescale.com/files/sensors/doc/data_sheet/MPL3115A2.pdf

v2:
* store 20-bit value in 32-bit buffer element (instead of 24-bit)
* zero buffer to prevent kernel data leak to userspace
* fix mutex unlock in trigger handler (thanks Andi Shyti)

This patch fixes the bug in reset_store caused by accessing NULL pointer.

The bdev gets its value from bdget_disk() which could fail when memory
pressure is severe and hence can return NULL because allocation of
inode in bdget could fail.

Hence, this patch introduces a check for bdev to prevent reference to a
NULL pointer in the later part of the code. It also removes unnecessary
check of bdev for fsync_bdev().

The ft1000 usb driver ignores expected Linux error codes, and uses two
values defined in ft1000_usb.h: STATUS_SUCCESS 0, and STATUS_FAILURE
0x1001; and sometimes -1. This patch changes the return values of the
function scram_start_dwnld to match the status of the handshake returned
by its helper functions, get_handshake and get_handshake_usb. If the
handshake fails, -ENETRESET is returned instead of the inappropriate
STATUS_FAILURE. Also, a new test has been added to differentiate failure
due to timeout from failure due to net reset (the default). -ETIMEDOUT
is returned in this case. Finally, 0 is returned on success instead of
STATUS_SUCCESS.
