Make "forcecrt2type" to apply also for XG21. The patch enables user to switch LVDS LCD ON/OFF without the need to update the video BIOS. Signed-off-by:

Delete XGI21_LCDCapList. This data is display specific and does not belong to the driver. It should be provided by the video BIOS. Signed-off-by:

XG27 has the second display output already hardcoded to disabled. Just in case, ensure that it has the LVDS code paths disabled. This will simplify the future cleanups. Signed-off-by:

We need the video BIOS only on XG21 and only during the init, so let's do everything at the same place. Signed-off-by:

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:
