From: Colin Ian King <colin.king@canonical.com>
Don't populate the array mapping on the stack but instead make it static. Makes the object code smaller by 79 bytes.
Before: text data bss dec hex filename 27572 2096 0 29668 73e4 drivers/media/pci/cx18/cx18-ioctl.o
After: text data bss dec hex filename 27429 2160 0 29589 7395 drivers/media/pci/cx18/cx18-ioctl.o
(gcc version 9.2.1, amd64)
