ADV7604_FMT_CHANGE events was debounced in adv7604_isr() to avoid that a receiver with a unstable input signal would block the event handling for other inputs. This solution was prone to errors. A better protection agains interrupt blocking is to delay the call of the interrupt service routine in the adv7604 driver if too many interrupts are received within a given time. Signed-off-by:

If the input is ADV7604_INPUT_VGA_RGB and RGB quantization range is set to V4L2_DV_RGB_RANGE_AUTO, video with CEA timings will be received as RGB. For ADV7604_INPUT_VGA_COMP, automatic CSC mode will be selected. See table 44 on page 205 in "ADV7604 Hardware Manual, Rev. F, August 2010" for details. Signed-off-by:

Whenever the hotplug pin is pulled low the chip resets a whole bunch of registers. It turns out that this can be turned off on the adv7511. Do so, as this 'feature' introduces race conditions in setting up registers, particular when the hotplug pin bounces a lot. Signed-off-by:

When em28xx extensions are loaded/removed, there are two locks: a single static em28xx_devlist_mutex that registers each extension and the struct em28xx dev->lock. When extensions are registered, em28xx_devlist_mutex is taken first, and then dev->lock. Be sure that, when extensions are being removed, the same order will be used. Reviewed-by:

The spin_lock_irqsave() macro is not nestable. The second call will overwrite the first record of "flags" so the IRQs will not be enabled correctly at the end of the function. In the current code, this function is always called from the IRQ handler so everything works fine and this fix doesn't change anything. Signed-off-by:

Smatch complains here because name is a 32 character buffer and we adding the "OMAP4 ISS " prefix as well for a total of 42 characters. The sd->name buffer can only hold 32 characters. I've changed it to use snprintf() to silence the overflow warning. Also I have removed the call to strlcpy() which is a no-op. Signed-off-by:
