[PATCH v2 0/4] soc: qcom: ice: fix dev reference leaked through of_qcom_ice_get

[Tudor Ambarus]

Hi!

Recently I've been pointed to this driver for an example on how consumers
can get a pointer to the supplier's driver data and I noticed a leak.

Callers of of_qcom_ice_get() leak the device reference taken by
of_find_device_by_node(). Introduce devm_of_qcom_ice_get().
Exporting qcom_ice_put() is not done intentionally as the consumers need
the ICE intance for the entire life of their device. Update the consumers
to use the devm variant and make of_qcom_ice_get() static afterwards.

This set touches mmc and scsi subsystems. Since the fix is trivial for
them, I'd suggest taking everything through the SoC tree with Acked-by
tags if people consider this fine. Note that the mmc and scsi patches
depend on the first patch that introduces devm_of_qcom_ice_get().

Thanks!
