2024-05-27samples: qmi: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2022-08-30soc: qcom: qmi: use const for struct qmi_elem_infoJeff Johnson1-5/+5
Currently all usage of struct qmi_elem_info, which is used to define the QMI message encoding/decoding rules, does not use const. This prevents clients from registering const arrays. Since these arrays are always pre-defined, they should be const, so add the const qualifier to all places in the QMI interface where struct qmi_elem_info is used. Once this patch is in place, clients can independently update their pre-defined arrays to be const, as demonstrated in the QMI sample code.

2020-11-25samples: qmi: Constify static qmi opsRikard Falkeborn1-2/+2
The only usage of qmi_sample_handlers[] and lookup_ops is to pass their addresses to qmi_handle_init() which accepts const pointers to both qmi_ops and qmi_msg_handler. Make them const to allow the compiler to put them in read-only memory.

2018-02-13samples: Introduce Qualcomm QMI sample clientBjorn Andersson2-0/+623
Introduce a sample driver that register for server notifications and spawn clients for each available test service (service 15). The spawned clients implements the interface for encoding "ping" and "data" requests and decode the responses from the remote.
