This implements more granular locking in vme_user_ioctl() by using separate
locks for each devfs device.
This also provides a synchronization between vme_user_read(), vme_user_write()
and vme_user_ioctl().

The tsi148 driver is registering the slave images as supporting the "USER"
access modes and CR/CSR access mode rather than the master images as it
should.
Remove the incorrect case entries for these modes from the

We also make sure that user won't be able to reconfigure the window while it is

Dear all,
mmap() on VME bridge devices is a feature present in many existing Linux and
UNIX drivers. The proposed solution follows the approach so that mmap()
offsets are coherent with read() and write() offsets, which seems to be the
only manner compatible with the current vme_user API. It also

I'm sorry this one doesn't make any sense. ??? Take the weekend off.
Have your co-workers review the patch on Monday. Then resend.

Thanks for the patch.
Please split it in two patches: one for ipuv3-crtc.c and another
Replaced "cleanups" in the struct parser_init_guts with err_rgn,
err_ctx, and out_rgn. The purpose is to remove redundant code and
have proper error handling. Put "goto out_rgn" on lin 108 because
there was no "out_ctx".

attached patch applies value of pixelclk-active

Better, but it still needs more work.
