This change fixes the unaligned access problem on debug offset by properly aligning it.

If the number of cea blocks are more than the supported blocks kernel information leak is possible by reading more data than is present in edid_buf.

If the user provides a value of "0" for "count", then kmalloc would not return NULL, but also there will be a memory block of "zero" size. This can lead to buffer overflows. Also trying to access invalid memory will cause kernel crashes. Ensure to check that the number of bytes to be written is non-zero. If zero, return invalid input.

Different modules can query for multiple resolution details based on the resolution ids received from EDID of the TV. In case resolution details exceed PAGE_SIZE, reuse res_info to get remaining timing details by provide page details. Check page id is within the max supported resolution ids to avoid reading extra memory than required.
