| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The member reg_cache is not used at all and therefore it should be removed. This member was usually needed for older versions of ASoC that did not handle caching automatically and had to be done in the driver itself.

The driver deals with much shorter times (<200ms). This will fix a rare division by zero bug in Mode1. This could happen, when the work is not executed in time (within mode1_latency) after the interrupt. In this case the DAC33 will not receive the needed nSample command in time, and enters to an unknown state, and won't recover. In such event the time window will increase, and eventually going to be bigger than 1s, resulting devision by zero.

The convention is intended to reduce text usage by sharing the common bits of the string, but the implementation is inherently fragile (a change to one format string but not the other will nullify any possible advantage), it isn't necessarily a net win depending on what this compiler does, and it it reduces code readability.

So make sure we only request the pin on the first setup of a SPI device. Otherwise, if you attempts to reconfigure a SPI device on the fly (like change bit sizes), the setup function incorrectly fails.

The AD7879 data available interrupt signals (DAV) completion, however some X,Y values are not valid because the screen inputs were floating during the acquisition. The AD7877 acts differently here, since it only asserts DAV if the touch is still present when the conversion sequence finished. Based on the fact that this can only happen in the last sample of the repeated conversion sequence, we simply skip the last (short glitches are filtered by the AD7879 internal median and average filters). This doesn't cause noticeable side effects, since the minimum conversion interval is 9.44ms. We receive ~100 waypoint samples per second, so we simply delay the result by 9.44ms. We also reject samples where pressure is greater than pressure_max. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

If qla4xxx_cmd_wait is then called from qla4xxx_eh_host_reset, we will always fail, because if the driver calls scsi_done then the the block layer will fail at blk_complete_request's blk_mark_rq_complete call instead of calling the normal completion path including the function, blk_queue_end_tag, which releases the tag.

Scatter-gather enables a write/read of multiple none-contiguous areas of an object, in a single call. The extents may overlap and/or be in any order. The Scatter-Gather list is sent to the target in what is called a "cdb continuation segment". This is yet another possible segment in the osd-out-buffer. It is unlike all other segments in that it sits before the actual "data" segment (which until now was always first), and that it is signed by itself and not part of the data buffer. This is because the cdb-continuation-segment is considered a spill-over of the CDB data, and is therefor signed under OSD_SEC_CAPKEY and higher. TODO: A new osd_finalize_request_ex version should be supplied so the @caps received on the network also contains a size parameter and can be spilled over into the "cdb continuation segment". Thanks to John Chandy <john.chandy@uconn.edu> for the original code, and investigations. And the implementation of SG support in the osd-target.
