When updating the scan mask we have to check the actual scan mask for if the channel is already enabled, not the matching scan mask from the available scan masks. The bit will already be set there and as a result the actual scan mask will not get updated and the channel stays disabled. Also fix the return value of iio_scan_el_store which would return 1 instead of the number of bytes written if the channel was already active in the scan mask. Acked-by:

The sw_ring does not properly handle the case where the write pointer already has wrapped around, the read pointer has not and the remaining buffer space at the end is enough to fill the read buffer: +-----------------------------------+ | | |##data##| | +-----------------------------------+ write_p read_p In this case the current code will copy all available data to the buffer and as a result will write beyond the bounds of the buffer and cause a memory corruption. To address this issue this patch adds code to calculate the available buffer space and makes sure that the number of bytes to copy does not exceed this number. This allows the code which copies the data around to be simplified as it only has to consider two cases: Read wraps around and read does not wrap around. Signed-off-by: -

Obviously drivers should only use this for pushing to buffers. They need buffer->scan_mask for pulling from them post demux. Signed-off-by:

These callbacks should not be buffer instance specific. Hence move them out of the buffer. Signed-off-by:

This gives you only what you ask for which is handy for some devices with weird scan combinations. Routes all data flow through a core utility function. That and this demuxing support will be needed to do demuxing to multiple destinations in kernel. Signed-off-by:

Also introduces active_scan_mask storage to tell the core what is really being currently captured from the device (different from what is desired as often has bonus channels). Signed-off-by:

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_register_driver() so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by: -
