Since commit cdd30ebb1b ("module: Convert symbol namespace to string
literal") the namespace has to be a string. Fix accordingly.

In addition to the macros EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(), that allow
exporting of kernel symbols to the kernel symbol table, variants of these are
available to export symbols into a certain namespace: EXPORT_SYMBOL_NS() and
EXPORT_SYMBOL_NS_GPL(). They take one additional argument: the namespace.
Please note that due to macro expansion that argument needs to be a
preprocessor symbol. E.g. to export the symbol ``usb_stor_suspend`` into the
EXPORT_SYMBOL_NS_GPL(). They take one additional argument: the namespace as a
string constant. Note that this string must not contain whitespaces.
E.g. to export the symbol ``usb_stor_suspend`` into the
namespace ``USB_STORAGE``, use::
EXPORT_SYMBOL_NS(usb_stor_suspend, "USB_STORAGE");
