  By moving support for the USB Syntek DC1125 Camera to staging, the
dependencies on MEDIA_USB_SUPPORT and MEDIA_CAMERA_SUPPORT were lost.

Hi Geert,

Patch itself looks good but we have some style issue. Applying this
patch I got the following warning from checkpatchl:

WARNING: Please use correct Fixes: style 'Fixes: <12 chars of sha1> ("<title line>")' - ie: 'Fixes: 56280c64ecac ("media: stkwebcam: deprecate driver, move to staging")'
#10: 

You have to pass only the first 12 chars of the sha1 commit into Fixes
msg:

Use:

 Fixes: 56280c64ecac ("media: stkwebcam: deprecate driver, move to staging")

Instead of:

 Fixes: 56280c64ecacc971 ("media: stkwebcam: deprecate driver, move to staging")

Thanks & Regards,
Tommaso

I always use 16 chars, to avoid these becoming ambiguous in a few years.

If we assume hashes are randomly distributed and that people commit
100k patches every year then with 12 character we would have 17
collisions every 1000 years.

So I can expect to see a collision before my retirement day
(which coincides with the signed 32-bit time_t flag day ;-)

BTW, does the above take into account that commit hashes can
collide with other object type hashes, too?

I assumed that `git show` won't show those other object types, but I
don't really know if that's true.

"git show" is not limited to commit types:
