[PATCH][RESEND] HID: elan: Make array buf static, shrinks object size

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Don't populate the array buf on the stack but instead make it
static. Makes the object code smaller by 43 bytes:

Before:
   text    data     bss     dec     hex filename
   7769    1520       0    9289    2449 drivers/hid/hid-elan.o

After:
   text    data     bss     dec     hex filename
   7662    1584       0    9246    241e drivers/hid/hid-elan.o

(gcc version 8.2.0 x86_64)
