This patch fixes stack corruption bug present in af9015_eeprom_dump():
the buffer buf is one byte smaller than required - there is 4 chars
for address prefix, 16*3 chars for dump of 16 eeprom bytes per line
and 1 byte for zero ending the string required, i.e. 53 bytes, but
only 52 are provided.
The one byte missing in stack based buffer buf causes following oops
on MIPS little endian platform, because i2c_adap pointer in
af9015_af9013_frontend_attach() is corrupted by inlined function
af9015_eeprom_dump():

See bug: http://bugzilla.kernel.org/show_bug.cgi?id=13385

Fix a regression caused by changeset 9133:64aed7485a43 - v4l: disconnect
kernel number from minor
Before the above changeset, ov511_probe used to allow forcing to use a
certain specific set of video devices, like:
modprobe ov511 unit_video=4,1,3 num_uv=3
So, assuming that you have 5 ov511 devices, and connect they one by one,
they'll gain the following device numbers (at the connection order):
/dev/video4
/dev/video1
/dev/video3
/dev/video0
/dev/video2
However, this was changed due to this change at video_register_device():
+ nr = find_next_zero_bit(video_nums[type], minor_cnt, nr == -1 ? 0 : nr);
With the previous behavior, a trial to register on an already allocated mirror
would fail, and a loop would get the next requested minor. However, the current
behavior is to get the next available minor instead of failing. Due to that,
this means that the above modprobe parameter will give, instead:
/dev/video5
/dev/video6
/dev/video7
/dev/video8
/dev/video9
In order to restore the original behavior, a static var were added,
storing the amount of already registered devices.
While there, it also fixes the locking of the probe/disconnect functions.
