drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error
[ Upstream commit 46d7ebfe6a75a454a5fa28604f0ef1491f9d8d14 ]
Ensure index in rtl2830_pid_filter does not exceed 31 to prevent
out-of-bounds access.
dev->filters is a 32-bit value, so set_bit and clear_bit functions should
only operate on indices from 0 to 31. If index is 32, it will attempt to
access a non-existent 33rd bit, leading to out-of-bounds access.
Change the boundary check from index > 32 to index >= 32 to resolve this
issue.
