Subject: linux-next: build warnings after merge of the input tree

Hi Dmitry,

After merging the input tree, today's linux-next build (powerpc
allyesconfig) produced these warnings:

drivers/input/touchscreen/atmel_mxt_ts.c: In function 'mxt_read_t9_resolution':
drivers/input/touchscreen/atmel_mxt_ts.c:1043:2: warning: passing argument 1 of '__swab16s' makes pointer from integer without a cast [enabled by default]
  le16_to_cpus(range.x);
