Jacob von Chorus d3b2a8800d staging: gs_fpgaboot: change char to u8
The bitstream storage variables were changed from char to u8 arrays to
prevent issues such as negative lengths. This change makes the code
compatible with the "data" field in "struct firmware" which is of type
u8.

Jacob von Chorus a46393aba7 staging: gs_fpgaboot: add buffer overflow checks
Four fields in struct fpgaimage are char arrays of length MAX_STR (256).
The amount of data read into these buffers is controlled by a length
field in the bitstream file read from userspace. If a corrupt or
malicious firmware file was supplied, kernel data beyond these buffers
can be overwritten arbitrarily.

This patch adds a check of the bitstream's length value to ensure it
fits within the bounds of the allocated buffers. An error condition is
returned from gs_read_bitstream if any of the reads fail.

This patch fixes the checkpatch.pl warning:

Foundation's mailing address from the sample GPL notice. The FSF has
changed addresses in the past, and may do so again. Linux already

gs_fpgaboot/gs_fpgaboot.c:376:44: error: macro "__TIMESTAMP__" might prevent reproducible builds [-Werror=date-time]
