[PATCH][next] media: vivid: fix potential integer overflow on left shift

2019-06-24 Thread Colin King
From: Colin Ian King There is a potential integer overflow when int 2 is left shifted as this is evaluated using 32 bit arithmetic but is being used in a context that expects an expression of type s64. Fix this by shifting 2ULL to avoid a 32 bit overflow. Addresses-Coverity: ("Unintentional int
