The .link_setup() handler uses state->lock to protect the src_sd field. This is only used in mipi_csis_s_stream(), which can't race .link_setup() as the MC core prevents link setup when the pipeline is streaming. Drop the lock. Signed-off-by:

The reset-names property is incorrect, as it references the reset of the MIPI D-PHY master, which is used by the DSI controller. Fixing the property name would create backward-compatibility issues. As the device has a single reset, we can instead drop reset-names completely, which also simplifies the binding. Fix the example accordingly to use the correct reset. Signed-off-by:

If some error occurs, URB buffers should also be freed. If they aren't freed with the dvb here, the em28xx_dvb_fini call doesn't frees the URB buffers as dvb is set to NULL. The function in which error occurs should do all the cleanup for the allocations it had done. Tested the patch with the reproducer provided by syzbot. This patch fixes the memleak. Reported-by:

The currently used functions for converting the transmission mode and guard interval from the internal values to the DVBv5 API values do not return correct values for ISDB broadcasts: - The raw (debugfs) transmission mode is an integer whose values can be 1, 2 or 3, that corresponds to 2K, 4K and 8K FFT modes respectively. However sms_to_mode() expects values 2, 4 or 8. - Guard interval, as defined by smscoreapi.h returns "1 divided by value" instead of 0, 1, 2, and 3 as defined in sms_to_guard_interval_table(). This commit implements ISDB-T specific methods for converting the internal values for the aforementioned parameters to the DVBv5 API values. It also adds support for reporting FEC and time interleaving values for each one of the layers.
