2018-03-21media: vb2-core: vb2_ops: document non-interrupt-context callingLuca Ceresoli
Driver writers can benefit in knowing if/when callbacks are called in interrupt context. But it is not completely obvious here, so document it.

Do not stop/restart dma on overrun or errors. Dma will be restarted on current frame transfer completion. Frame transfer completion is ensured even if overrun or error occurs by DCMI continuous capture mode which restarts data transfer at next frame sync. Do no warn on overrun while in irq thread, this slows down system and lead to more overrun errors. Use a counter instead and log errors at stop streaming.

Add a function (as well as a helper macro) to obtain the best size in a list of device specific sizes. This helps writing drivers as well as aligns interface behaviour across drivers. The struct in which this information is contained in is typically specific to the driver, therefore the existing function v4l2_find_nearest_format() does not address the need.

2018-03-07media: dvbdev: fix building on ia64Mauro Carvalho Chehab
Not sure why, but, on ia64, with Linaro's gcc 7.3 compiler, using #ifdef (CONFIG_I2C) is not OK. So, replace it by IS_ENABLED(CONFIG_I2C), in order to fix the builds there. Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
