2022-05-27HID: amd_sfh: Don't show client init failed as error when discovery failsMario Limonciello1-1/+2
When sensor discovery fails, this means that the system doesn't have any sensors connected and a user should only be notified at most one time. A message is already displayed at WARN level of "failed to discover, sensors not enabled". It's pointless to show that the client init failed at ERR level for the same condition.

- dead code elimination (Christophe JAILLET)
2022-02-14HID: amd_sfh: Add interrupt handler to process interruptsBasavaraj Natikar2-0/+41
On newer AMD platforms with SFH, it is observed that random interrupts get generated on the SFH hardware and until this is cleared the firmware sensor processing is stalled, resulting in no data been received to driver side.

2021-05-27HID: amd_sfh: Use devm_kzalloc() instead of kzalloc()Basavaraj Natikar2-12/+9
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.
