[BUG 0/5] bug reports for atomisp to make it work

[Tsuchiya Yuto]

Hi all,

These mails contain RFC patches, which are almost bug report and some
are just bug report, for atomisp to work (again). Tested on Microsoft
Surface 3 (Windows) and Xiaomi Mi Pad 2 (Android model) with v5.15-rc5.
Both are Cherry Trail (ISP2401) devices.

I'm still not used to Linux patch sending flow. Sorry in advance
if there is some weirdness :-) but I did my best.

To try to take a picture, take a look at the series I sent earlier named
("various fixes for atomisp to make it work")

The 1st patch is required to take a picture with atomsip (again):

    [BUG][RFC] media: atomisp: pci: assume run_mode is PREVIEW

The 2nd patch is to avoid kernel warning message:

    [BUG][RFC] media: atomisp: pci: remove dummy_ptr NULL check to avoid
      duplicate active_bo

The 3rd patch is to avoid kernel oops, which is almost required for
using atomisp normally:

    [BUG][RFC] media: atomisp: pci: add NULL check for asd obtained from
      atomisp_video_pipe

The 4th-5th mail is bug reports, no patches for these issues yet:

    [BUG] media: atomisp: `modprobe -r` not working well (dup video4linux,
      ATOMISP_SUBDEV_{0,1})
    [BUG] media: atomisp: atomisp causes touchscreen to stop working on
      Microsoft Surface 3

I added further descriptions at the top of each RFC/BUG mails.

Regards,
Tsuchiya Yuto
