Clang points out a code path that returns an undefined value
in an error case:
sound/soc/fsl/imx-hdmi.c:165:6: error: variable 'ret' is used uninitialized
whenever 'if' condition is true [-Werror,-Wsom
etimes-uninitialized]
if ((hdmi_out && hdmi_in) || (!hdmi_out &&

I noticed that iounmap() of msgr_block_addr before return from
mpic_msgr_probe() in the error handling case is missing. So use
devm_ioremap() instead of just ioremap() when remapping the message

This is way to catch some cases of decrementer overflow, when the
decrementer has underflowed an odd number of times, while MSR[EE] was
disabled.
With a typical small decrementer, a timer that fires when MSR[EE]
