Subject: [PATCH 2/2] atm: solos-pci: constify attribute_group structures

Functions working with attribute_groups provided by <linux/sysfs.h>
work with const attribute_group. These attribute_group structures do not
change at runtime so mark them as const.

File size before:
text data bss dec hex filename
35740 28424 832 64996 fde4 drivers/atm/solos-pci.o

File size after:
text data bss dec hex filename
35932 28232 832 64996 fde4 drivers/atm/solos-pci.o

This change was made with the help of Coccinelle.
