The usecase where, user allocates small size of buffer through bootargs (video1_bufsize/video2_bufsize) and later from application tries to set the format which requires larger buffer size, driver doesn't check for insufficient buffer size and allows application to map extra buffer. This leads to kernel crash, when user application tries to access memory beyond the allocation size. Added check in both mmap and reqbuf call back function, and return error if the size of the buffer allocated by user through bootargs is less than the S_FMT size.
