regulator: da9055: Constify static data
Driver does not modify static data with regulators description (struct da9055_regulator_info), so make it const for code safety. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://patch.msgid.link/20240909-regulator-const-v1-2-8934704a5787@linaro.org Signed-off-by: Mark Brown <broonie@kernel.org>
