Dan Carpenter 80eab6a9df PM / devfreq: mtk-cci: Fix potential error pointer dereference in probe() ...

[ Upstream commit fc33bf0e09 ]

The drv->sram_reg pointer could be set to ERR_PTR(-EPROBE_DEFER) which
would lead to a error pointer dereference.  Use IS_ERR_OR_NULL() to check
that the pointer is valid.
