[PATCH v3 0/2] Add SPI support for Diolan DLN2

[Laurentiu Palcu <laurentiu.palcu-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

Short note: I couldn't see the 2nd patch applied in any mfd tree, so I
included it again.

Changes in v3:
 * fixed some coding style problems;
 * do not use dln2->buf for small commands, use the stack;
 * removed a bunch of __packed attributes that were not really needed;
 * change the copy from/to buffer routines to use put/get_unaligned
   macros to avoid potential buffer alignment issues;

Changes in v2:
 * fixed an indentation issue;
 * removed redundant call to spi_master_put() in _remove();

Hi,

This patchset adds support for the SPI module of the Diolan DLN2 USB to
I2C/SPI/GPIO bridge [1].

This patch depends on another patchset, [1], not yet merged, which adds support
for the other two modules: I2C and GPIO.
