fsicom: Import dma buffer apis with namespace
...
fsicom driver uses the dma buffer which were exported
as EXPORT_SYMBOL_GPL() till K5.15. From k5.16, it is exported
with namespace i.e. EXPORT_SYMBOL_NS_GPL(). This change
needs to import namespace in fsicom driver for K5.16 onwards.
Add support for this.
