pinctrl: samsung: Use unsigned int for number of controller IO mem resources
Number of IO memory resources cannot be negative obviously and the driver depends silently on this (by iterating from 0 to nr_ext_resources+1). Make this requirement explicit. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Reviewed-by: Sylwester Nawrocki <s.nawrocki@samsung.com>
