Subject: [PATCH v2] regulator: core: Update regulator_is_supported_voltage for fixed voltages

Commit c5f3939b8fe0 ("regulator: core: Support fixed voltages in
regulator_is_supported_voltage()") returns success when the regulator
voltage is less than both min_uV and max_uV. Modify this to return
success only when the regulator voltage is within the specified range.

Signed-off-by: Tushar Behera <tushar.behera@...aro.org>

Changes since v1:
	* Return success when the regulator voltage is within the
	specified range.
