[PATCH] hwmon: (asc7621): make several arrays static const

From: Colin King
Date: Wed Aug 30 2017 - 04:33:07 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the arrays on the stack, instead make them static.
Makes the object code smaller by over 950 bytes:

Before:
text data bss dec hex filename
26144 18768 352 45264 b0d0 drivers/hwmon/asc7621.o

After:
text data bss dec hex filename
25029 18928 352 44309 ad15 drivers/hwmon/asc7621.o
