This patch fixes the checkpatch.pl warning :
WARNING: else is not generally useful after a break or return
Expressions under 'else' branch in function 'gc0310_s_power' are
executed whenever the exppression in 'if' is False. Otherwise, return
from function occurs. Therefore, there is no need in 'else', and it has
been removed.

Inside alloc_user_pages() based on flag value either pin_user_pages()
or get_user_pages_fast() will be called. However, these API might fail.
But free_user_pages() called in error handling path doesn't bother
about return value and will try to unpin bo->pgnr pages, which is
incorrect.
Fix this by passing the page_nr to free_user_pages(). If page_nr > 0
pages will be unpinned based on bo->mem_type. This will also take care
of non error handling path.

the kAPI for a frontend can use 3 different tuning methods:
1. The hardware tracks internally frequency shifts via its
own internal zigzag logic;
2. The hardware has a custom zigzag method, implemented via
fe search() ops;
3. The hardware doesn't have any internal zigzag logic. So,
the Kernel needs to implement it.
Drivers that use the in-kernel software zigzag are required to
provide some parameters for the zigzag code to work. Failing
to do that will just make the Kernel to tune several times
to the very same frequency, delaying the tuning time for
no good reason. This is actually a kAPI violation
(and an uAPI one, as the frequency shift is exported to the
uAPI).
Emit a warning on such case, as the driver needs to be fixed.

The VIDIOC_G/S/TRY_EXT_CTRLS documentation has large explanatory texts for
some of the fields in a table. This makes it hard to read. Move those text
to a new cell spanning the whole width of the table, similar to what was
done for struct v4l2_pix_format. This makes it much more readable.
Also move the 'ctrl_class' description to below the 'which' description and
just mention that it is deprecated and that 'which' should be used instead.
Finally remove 'note::' for the V4L2_CTRL_WHICH_DEF_VAL description. It
doesn't have to be marked as a note, it's just a simple paragraph.
