We read the eeprom anyway for dumping. Switch the dumping to
print_hex_dump_bytes and compute hash above that by
hash = 0;
for (u32 VAL) in (eeprom):
hash *= GOLDEN_RATIO_PRIME_32
hash += VAL; // while preserving endinaness

When using VIDIOC_QBUF with memory type set to V4L2_MEMORY_MMAP, the
v4l2_buffer buffer gets unmodified on drivers like uvc (well, only
bytesused field is modified). Then some apps like gstreamer are reusing
the same buffer later to call munmap (eg passing the buffer "length"
field as 2nd parameter of munmap).
It's working fine on full 32bits but on 32bits systems with 64bit
kernel, the get_v4l2_buffer32() doesn't copy length/m.offset values and
then copy garbage to userspace in put_v4l2_buffer32().
This has for consequence things like that in the libv4l2 logs:
libv4l2: v4l2 unknown munmap 0x2e2b0000, -2145144908
libv4l2: v4l2 unknown munmap 0x2e530000, -2145144908
The buffer are not unmap'ed and then if the application close and open
again the device, it won't work and logs will show something like:
libv4l2: error setting pixformat: Device or resource busy
The easy solution is to read length and m.offset in get_v4l2_buffer32().

FCP transactions as well as CMP transactions were serialized with
mutex_lock_interruptible. It is extremely unlikly though that a signal
will arrive while a concurrent process holds the mutex. And even if one
does, the duration of a transaction is reasonably short (1.2 seconds if
all retries time out, usually much shorter).
Hence simplify the code to plain mutex_lock.

This is a portability fix and reduces stack usage.
The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet
payload buffers in firedtv (payload of write requests in avc_write and
of lock requests in cmp_lock) to slab-allocated memory.
We use the 512 bytes sized FCP frame buffer in struct firedtv for this
purpose. Previously it held only incoming FCP responses, now it holds
pending FCP requests and is then overwriten by an FCP response from the
tuner subunit. Ditto for CMP lock requests and responses. Accesses to
the payload buffer are serialized by fdtv->avc_mutex.
As a welcome side effect, stack usage of the AV/C transaction functions
is reduced by 512 bytes.
Alas, avc_register_remote_control() is a special case: It previously
did not wait for a response. To fit better in with the other FCP
transactions, let it wait for an interim response.
