Subject: [PATCH v3 6/8] media: atomisp: remove compat_ioctl32 code
From: Arnd Bergmann <arnd@...db.de>
This is one of the last remaining users of compat_alloc_user_space()
and copy_in_user(), which are in the process of getting removed.
As of commit 57e6b6f2303e ("media: atomisp_fops.c: disable
atomisp_compat_ioctl32"), nothing in this file is actually getting used
as the only reference has been stubbed out.
Remove the entire file -- anyone willing to restore the functionality
can equally well just look up the contents in the git history if needed.

for this driver until the other work is done, as there will be a lot
of code churn until this driver becomes functional again.
+16. Fix private ioctls to not need a compat_ioctl handler for running
+ 32-bit tasks. The compat code has been removed because of bugs,
+ and should not be needed for modern drivers. Fixing this properly
