X-Git-Tag: microblaze-v6.13~68^2~2^2~13
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=83b6549ee18885c1ac74ae91a7e406e7ed33b5c8;p=linux-2.6-microblaze.git

Input: zforce_ts - switch to using get_unaligned_le16

Instead of doing conversion from little-endian data to CPU endianness
by hand use existing helpers.
