cpufreq: speedstep-lib: make several arrays static, makes code smaller
Don't populate arrays on the stack, instead make them static. Makes the object code smaller by over 860 bytes: Before: text data bss dec hex filename 10716 5196 0 15912 3e28 drivers/cpufreq/speedstep-lib.o After: text data bss dec hex filename 9690 5356 0 15046 3ac6 drivers/cpufreq/speedstep-lib.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Rafael J.
