'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c564 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

Since moving the message buffers off the stack, the dynamically allocated get-prop-descriptor request buffer is incorrectly sized due to using the pointer rather than request-struct size when creating the operation. Fortunately, the pointer size is always larger than this one-byte request, but this could still cause trouble on the remote end due to the unexpected message size.

usleep_range() is called in non-atomic context so there is little point in setting min==max as the jitter of hrtimer is determined by interruptions anyway. usleep_range can only perform the intended coalescence if some room for placing the hrtimer is provided. Given the range of milliseconds the delay will be 2+ anyway - so make it 2-2.5 ms which gives hrtimers space to optimize without negatively impacting performance.

Lars-Peter Clausen authored
For devices from the SigmaDelta family we need to keep CS low when doing a conversion, since the device will use the MISO line as a interrupt to indicate that the conversion is complete. This is why the driver locks the SPI bus and when the SPI bus is locked keeps as long as a conversion is going on. The current implementation gets one small detail wrong though. CS is only de-asserted after the SPI bus is unlocked. This means it is possible for a different SPI device on the same bus to send a message which would be wrongfully be addressed to the SigmaDelta device as well. Make sure that the last SPI transfer that is done while holding the SPI bus lock de-asserts the CS signal.

The sample frequency is driven using the oversampling ratio depending on the SPI bus frequency. Currently, oversampling ratio is computed by an entire division: - spi_freq / sample_freq. This may result in inaccurate value. Using DIV_ROUND_CLOSEST improves resulting sample frequency, which is useful for audio that requests fixed rates (such as: 8, 16 or 32 kHz). BTW, introduce new routine to re-factor sample frequency setting, and move frequency accuracy message from warning to debug level.
