WARNING: space prohibited between function name and open parenthesis '('
#101: FILE: include/linux/efi.h:976:
+extern int efi_mem_type (unsigned long phys_addr);
Please integrate scripts/checkpatch.pl in your patch creation workflow.
Some of the warnings/errors *actually* make sense.
I know, the other function prototypes have a space too but that's not
our coding style. Looks like this trickled in from ia64, from looking at
arch/ia64/kernel/efi.c.
