When building with -Wsometimes-uninitialized, Clang warns: drivers/iio/adc/stmpe-adc.c:204:13: warning: variable 'data' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] Clang can't tell that data will never be used uninitialized because the two if statements take care of all cases. Remove the first if statement and make it the else branch of the second one so that it is apparent to Clang that all cases are covered.

When building with -Wsometimes-uninitialized, Clang warns: drivers/iio/common/ssp_sensors/ssp_iio.c:95:6: warning: variable 'calculated_time' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] While it isn't wrong, this will never be a problem because iio_push_to_buffers_with_timestamp only uses calculated_time on the same condition that it is assigned (when scan_timestamp is not zero). While iio_push_to_buffers_with_timestamp is marked as inline, Clang does inlining in the optimization stage, which happens after the semantic analysis phase (plus inline is merely a hint to the compiler). Fix this by just zero initializing calculated_time. Link: https://github.com/ClangBuiltLinux/linux/issues/394Signed-off-by:

This driver's probe() uses a mix of devm_ and non-devm_ functions. This means that the remove order will not be the exact opposite of the probe order. Remove order: 1. remove() executes: iio_device_unregister iio_triggered_buffer_cleanup iio_trigger_unregister (A) 2. core frees devm resources in reverse order: free_irq iio_trigger_free iio_device_free In (A) the trigger has been unregistered, but the irq handler is still registered and active, so the trigger may still be touched via interrupt -> as3935_event_work. This is a potential use-after-unregister. Given that the delayed work is never canceled explicitly, it may run even after iio_device_free. This is a potential use-after-free. Solution: convert all probe functions to their devm_ equivalents. Add a devm callback, called by the core on remove right after irq_free, which explicitly cancels the delayed work. This will guarantee that all resources are freed in the correct order. As an added bonus, some boilerplate code can be removed. Signed-off-by:

Currently mount matrix is allowed in Device Tree, though there is no technical issue to extend it to support ACPI. Convert the function to use device_property_read_string_array() and thus allow to read mount matrix from ACPI if available. Example of use in _DSD method: Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () { "mount-matrix", Package() { "1", "0", "0", "0", "0.866", "0.5", "0", "-0.5", "0.866", } }, } }) At the same time drop the "of" prefix from its name and convert current users. No functional change intended. Signed-off-by: -
