2015-05-01[media] v4l2: replace try_mbus_fmt by set_fmtHans Verkuil
The try_mbus_fmt video op is a duplicate of the pad op. Replace all uses in sub-devices by the set_fmt() pad op. Since try_mbus_fmt and s_mbus_fmt both map to the set_fmt pad op (but with a different 'which' argument), this patch will replace both try_mbus_fmt and s_mbus_fmt by set_fmt.

2015-05-01[media] marvell-ccic: use vb2 helpers and core lockingHans Verkuil
Use the V4L2 core locking system instead of rolling your own. Switch to the vb2 fop and ioctl helpers to get rid of a lot of code. This also made it easy to add VB2_READ to the DMA modes, since you get read() for free with vb2 and these helpers. Finally remove the users field: this information is also available from the core framework, no need to keep track of it in the driver.

2015-05-01[media] marvell-ccic: control handler fixesHans Verkuil
No controls were reported, even though the ov7670 does have controls. Two reasons for this: the v4l2_ctrl_handler_init() call must come before the ov7670 is loaded (otherwise the ov7670 won't know that its controls should be added to the bridge driver), and the v4l2_ctrl_handler_free() call at the end should only be called if the ret value is non-zero (otherwise you would just free all the controls that were just added).

Currently vb2 core acquires mmap_sem just around call to __qbuf_userptr(). However since commit f035eb4e976ef5 (videobuf2: fix lockdep warning) it isn't necessary to acquire it so early as we no longer have to drop queue mutex before acquiring mmap_sem.

2015-05-01[media] v4l2-dv-timings: fix rounding error in vsync_bp calculationPrashant Laddha
Changed the rounding offsets used in vsync_bp calculation in cvt and gtf timings. The results for vsync_bp should now match with results from timing generator spreadsheets for cvt and gtf standards. In the vsync_bp calculation for cvt, always round down the value of (CVT_MIN_VSYNC_BP / h_period_est) and then add 1. It thus, reflects the equation used in timing generator spreadsheet. Using 1999999 as rounding offset, could pontentially lead to bumping up the vsync_bp value by extra 1. In the vsync_bp calculations for gtf, instead of round up or round down, round the (CVT_MIN_VSYNC_BP / h_period_est) to the nearest integer.

All masks for timings are different between ADV7604 and ADV7611. Most of the values have 1 precision bit more in the latter. Fix this by adding new fields to the chip_info structure.

2015-05-01[media] bttv: fix missing irq after reloading driverHans Verkuil
If pci_disable_device() isn't called when the driver is removed, then the next time when it is loaded the irq isn't found. I'm pretty sure this used to work in the past, but calling pci_disable_device() is clearly the correct method and this makes it work again.
