media: staging: atomisp: fix the uninitialized use in gc2235_detect()

Browse source

Inside function gc2235_detect(), variable "low" could be uninitialized
if ov5693_read_reg() returns error, however, it affects the value of
variable "id". The "id" is used in the later if statement, which is
potentially unsafe.
