required so, don't pass this null character to copy_to_user.

Video driver and firmware communicates over shared queue.
The queue header has the indices which synchronizes the read
and write between the driver and firmware modules.
This change ensures that the indices are within the valid
range before accessing them.

7a9cdebdcc17 ("mm: get rid of vmacache_flush_all() entirely") removed the
VMACACHE_FULL_FLUSHES statistics, but didn't remove the corresponding
entry in vmstat_text. This causes an out-of-bounds access in
vmstat_show().
Luckily this only affects kernels with CONFIG_DEBUG_VM_VMACACHE=y, which
is probably very rare.

commit 7a9cdebdcc17e426fb5287e4a82db1dfe86339b2 upstream.
Jann Horn points out that the vmacache_flush_all() function is not only
potentially expensive, it's buggy too. It also happens to be entirely
unnecessary, because the sequence number overflow case can be avoided by
simply making the sequence number be 64-bit. That doesn't even grow the
data structures in question, because the other adjacent fields are
already 64-bit.
So simplify the whole thing by just making the sequence number overflow
case go away entirely, which gets rid of all the complications and makes
the code faster too. Win-win.
[ Oleg Nesterov points out that the VMACACHE_FULL_FLUSHES statistics
also just goes away entirely with this ]

A fixed sink PDO request includes both operating current and
max current. Although the max current requested may be greater
than the available source advertisement, as per spec only the
operating current request needs to be considered. The sink will
likely have also set the Capability Mismatch bit as well. Hence,
don't reject the request otherwise the sink will keep
re-requesting and never enter a contract.
