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]
