[PATCH] iio: bmc150: Fix type of step transfer variable

[PATCH] iio: bmc150: Fix type of step transfer variable

[Markus Pargmann]

regmap_get_raw_read_max() returns type size_t. Also the later dev_err()
already uses the correct printk format "%zu".

This patch changes the type of 'step' to size_t.

Hi,

this problem was reported by the kbuild robot. This should fix the warning. I
am not sure if the patches are already in some public tree, otherwise this
could directly be squashed into the commit directly.

Thanks,

Markus

I'm not sure what happened here.  I haven't touched the tree since this report,
but the type is already size_t in my local tree. 

Anyhow, the issues seems not to exist anymore for some reason.
