staging: imx-drm: imx-tve: Check the return value of 'regulator_enable()'
Since commit c8801a8 (regulator: core: Mark all get and enable calls as __must_check) we need to check the value returned by 'regulator_enable()'. Do this check to get rid of the following build warning: drivers/staging/imx-drm/imx-tve.c: In function 'imx_tve_probe': drivers/staging/imx-drm/imx-tve.c:671:19: warning: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Wunused-result] Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
