* [media] media: davinci: vpif_display: drop setting of vb2 buffer state to ACTIVEPrabhakar Lad2014-09-21
| | | | | | | | | this patch drops setting of vb2 buffer state to VB2_BUF_STATE_ACTIVE, as any buffer queued to the driver is marked ACTIVE by the vb2 core.

* [media] videobuf: Allow reqbufs(0) to free current buffersHans de Goede2014-09-21
| | | | | | | | | | | | | | All the infrastructure for this is already there, and despite our desires for the old videobuf code to go away, it is currently still in use in 18 drivers. Allowing reqbufs(0) makes these drivers behave consistent with modern drivers, making live easier for userspace, see e.g. : https://bugzilla.gnome.org/show_bug.cgi?id=735660 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] videobuf2-core: take mmap_sem before calling __qbuf_userptrHans Verkuil2014-09-21
| | | | | | | | | | | | | | (Changes since v2: dropped local variable as suggested by Laurent) Commit f035eb4e976ef5a059e30bc91cfd310ff030a7d3 (videobuf2: fix lockdep warning) unfortunately removed the mmap_sem lock that is needed around the call to __qbuf_userptr. Amazingly nobody noticed this (especially me as the author) until Jan Kara pointed this out to me.

| | | | | | | | | | | | | | Old IT9135 AX needs a little bit different register settings for sleep than newer IT9135 BX. This has been broken always, as power management of the whole driver, but it started to be problem as I fixed clock. Earlier clock was disabled very first on sleep and rest of the commands were skipped by the chip as no clock, leaving tuner full power state. When I fixed clocks these PM bugs started raising out as I/O errors.
