Subject[PATCH] ssb: make array pwr_info_offset static const, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the array pwr_info_offset on the stack but instead make it
static const. Makes the object code smaller by 207 bytes.

Before:
text data bss dec hex filename
26066 3000 64 29130 71ca drivers/ssb/pci.o

After:
text data bss dec hex filename
25763 3096 64 28923 70fb drivers/ssb/pci.o

(gcc version 9.2.1, amd64)
