Subject: [PATCH] grub_dl_set_mem_attrs(): fix format string
The grub_dprintf() call for printing the message
updating attributes for GOT and trampolines
passes the argument "mod->name", but the format string doesn't accept that
argument.
Print the module name too.
Example output:
> kern/dl.c:736: updating attributes for GOT and trampolines ("video_fb")
Fixes: ad1b904d325b (nx: set page permissions for loaded modules.)
