[PATCH v3 00/17] media: rkisp1: Misc bug fixes and cleanups

[Laurent Pinchart]

Hello,

This series fixes multiple issues and performs further cleanups for the
rkisp1 driver.

Patches 01/17 to 07/17 fix issues in the error paths at probe time that
lead to kernel crashes in case of errors. The .remove() path is also
improved as a result.

Patches 08/17 and 09/17 then clean up register definitions, patch 10/17
swaps the arguments to rkisp1_write(), and patch 11/17 simplifies access
to the resizer registers.

Patches 12/17 to 16/17 move on to improving debugfs support, with code
first moved to a separate file (12/17) that can be conditionally
compiled (13/17), support for collecting statistics on the input
interface (14/17, very useful to check if the ISP actually receives
data) and for dumping core and ISP registers (15/17). Patch 16/17
completes that rework by moving the resizer register dumps support to
debugfs too.

Finally, patch 17/17 simplifies the V4L2 querycap implementation on
video nodes.

More fixes and improvements should follow, so I'd like to merge sooner
than latter if possible, to avoid having to rebase large series.
