2022-05-11HID: amd_sfh: Add physical location to HID deviceBasavaraj Natikar1-0/+5

2021-05-27HID: amd_sfh: Use devm_kzalloc() instead of kzalloc()Basavaraj Natikar1-3/+0
Replace kzalloc with devm_kzalloc in driver initialization sequence. The allocation can be tied to the lifetime of the amd_sfh driver. This cleans up an exit & error paths, since the objects does not need to be explicitly freed anymore.

2020-11-12SFH: fix error return check for -ERESTARTSYSColin Ian King1-3/+3
Currently the check for the error return code -ERESTARTSYS is dead code and never executed because a previous check for ret < 0 is catching this and returning -ETIMEDOUT instead. Fix this by checking for -ERESTARTSYS before the more generic negative error code.

2020-10-22SFH:Transport Driver to add support of AMD Sensor Fusion Hub (SFH)Sandeep Singh1-0/+174
To support AMD Sensor Fusion Hub (SFH) via the HID client's we need to register the client with the HID framework. Here we mostly address on how to register the client with the framework and define the interfaces for communication.
