Add __aligned(8) to ensure the buffer passed to iio_push_to_buffers_with_timestamp() is suitable for the naturally aligned timestamp that will be inserted. Here structure is not used, because this buffer is also used elsewhere in the driver. Fixes: 67e17300 ("iio: potentiostat: add LMP91000 support") Signed-off-by:

The samples buffer is passed to iio_push_to_buffers_with_timestamp() which requires a buffer aligned to 8 bytes as it is assumed that the timestamp will be naturally aligned if present. Fixes tag is inaccurate but prior to that likely manual backporting needed (for anything before 4.18) Earlier than that the include file to fix is drivers/iio/common/cros_ec_sensors/cros_ec_sensors_core.h: commit 974e6f02 ("iio: cros_ec_sensors_core: Add common functions for the ChromeOS EC Sensor Hub.") present since kernel stable 4.10. (Thanks to Gwendal for tracking this down) Fixes: 5a0b8cb4 ("iio: cros_ec: Move cros_ec_sensors_core.h in /include") Signed-off-by:

Variable location for the timestamp, so just use __aligned(8) to ensure it is always possible to naturally align it. Found during an audit of all calls of uses of iio_push_to_buffers_with_timestamp() Fixes tag is not accurate, but it will need manual backporting beyond that point if anyone cares.

To make code more readable, use a structure to express the channel layout and ensure the timestamp is 8 byte aligned. Found during an audit of all calls of uses of iio_push_to_buffers_with_timestamp(). Fixes tag is not strictly accurate as prior to that patch there was potentially an unaligned write. However, any backport past there will need to be done manually. Fixes: 0624bf84 ("iio:tcs3472: Use iio_push_to_buffers_with_timestamp()") Signed-off-by:

Remove() callback calls pm_runtime_put_noidle() but there it is not balancing a get. No actual affect because the runtime pm core prevents the reference count going negative. Whilst here use pm_runtime_resume_and_get() rather than open coded version. Again, coccinelle script missed this one due to more complex code structure. Signed-off-by:

Calls to pm_runtime_put_noidle in probe() error path and remove() are not match to any get() calls. The runtime pm core protects against negative reference counts, so this doesn't have any visible impact beyond confusing the reader. Whilst here use pm_runtime_resume_and_get() to replace boilerplate. Signed-off-by:

probe() error paths after runtime pm is enabled, should disable it. remove() should not call pm_runtime_put_noidle() as there is no matching get() to have raised the reference count. This case has no affect a the runtime pm core protects against going negative. Whilst here use pm_runtime_resume_and_get() to tidy things up a little. coccicheck script didn't get this one due to complex code structure so found by inspection. Signed-off-by:

The call to pm_runtime_put_noidle() in remove() is not balanced by a get so drop it. Using pm_runtime_resume_and_get() allows for simple introduction of error handling to allow for runtime resume failing. Signed-off-by:

1 instance found using coccicheck script under review at: https://lore.kernel.org/lkml/20210427141946.2478411-1-Julia.Lawall@inria.fr/ The other instance changed did not check for failure of the pm_runtime_get_sync() so that is added. Note the remaining pm_runtime_get_sync() call is left alone because it is not obvious what to do on failure to power up in remove() This is a prequel to taking a closer look at the runtime pm in IIO drivers in general.

Converts from using pm_runtime_get_sync() with no error handling over to pm_runtime_resume_and_get() which will ensure we don't end up holding a reference. Ensure this error return is then handled at calls to mlx90614_power_get(). These are all direct returns. Signed-off-by:

No point in calling pm_runtime_put_noidle() that isn't balancing a get. Note no actual impact because the runtime pm core protects against a negative reference counter. For the pm_runtime_resume_and_get() main interest is in clearing out this old pattern to avoid it getting coppied into new submissions. Signed-off-by:

Jonathan Cameron authored
This driver alls pm_runtime_put_noidle() in it's remove function, but there is no matching get call. This isn't a bug as runtime pm will not allow the reference counter to go negative, but it is missleading so lets remove it. Whilst here use pm_runtime_resume_and_get() to tidy up some boilerplate. The coccicheck script didn't get this one due to the less obvious structure. Found by inspection. Signed-off-by:

A call to pm_runtime_put_noidle() doesn't match any call that would result in a get(). It is safe because runtime pm core protects against the reference counter going 0, but it makes it harder to understand the code. Whilst here use pm_runtime_resume_and_get() to tidy things up. The Coccinelle script didn't get this one due to more complex code structure. Signed-off-by:
