[PATCH] scripts/gdb: fix lx-symbols 'gdb.error' while loading modules

[PATCH] scripts/gdb: fix lx-symbols 'gdb.error' while loading modules

[Stefano Garzarella]

Commit ed66f991bb19 ("module: Refactor section attr into bin
attribute") removed the 'name' field from 'struct module_sect_attr'
triggering the following error when invoking lx-symbols:

  (gdb) lx-symbols
  loading vmlinux
  scanning for modules in linux/build
  loading @0xffffffffc014f000: linux/build/drivers/net/tun.ko
  Python Exception <class 'gdb.error'> There is no member named name.:
  Error occurred in Python: There is no member named name.

This patch fixes the issue taking the module name from the 'struct
attribute'.

It might not be needed if this gets in to v5.8 in time, but perhaps:

Fixes: ed66f991bb19 ("module: Refactor section attr into bin attribute")

Otherwise, also looks fine to me.
