commit 105967ad68d2eb1a041bc041f9cf96af2a653b65 upstream.

gcc-7 points out an older regression:

drivers/staging/iio/resolver/ad2s1210.c: In function 'ad2s1210_read_raw':
drivers/staging/iio/resolver/ad2s1210.c:515:42: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]

The original code had 'unsigned short' here, but incorrectly got
converted to 'bool'. This reverts the regression and uses a normal
type instead.

Fixes: 29148543c521 ("staging:iio:resolver:ad2s1210 minimal chan spec conversion.")
