ASoC: imx-audmux: remove null check of audmux_base in audmux_read_file
When audmux_read_file is called, it means the driver is already initialised successfully, so we don't need to check audmux_base. It also fix smatch warning: sound/soc/fsl/imx-audmux.c:78 audmux_read_file() warn: possible memory leak of 'buf' Signed-off-by: Richard Zhao <richard.zhao@freescale.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
