[PATCH] iio:light:ltr501 bug in parameter sanity check.

[Jonathan Cameron <jic23@kernel.org>]

Clearly the intent was to error if the value was not 0 or 1.
As implemented we have (A != 0 || A != 1) which is always true
as A is never both 0 and 1 at the same time.

As the autobuilder suggested, && makes more sense for this error
check.

This is obvious enough that I'll probably apply it shortly whether or
not I get Acks.  However, Acks always good!
