Subject: [PATCH] staging/vt6656: Fix sparse warning constant 0xffffffff00000000U is so big it is unsigned long

Since 7c65fa2a4c176c9bfab1ef954c4cef005dd9fb8b
'staging: vt6656: Remove QWORD from source and replace with u64.'
a new sparse warning showed up:

'drivers/staging/vt6656/card.c:798:26: sparse: constant
 0xffffffff00000000U is so big it is unsigned long'

-> Append L to fix the warning.
