[PATCH v2 0/5] soc: qcom: fix rpm_requests module probing

[Dmitry Baryshkov]

The GLINK RPMSG channels get modalias based on the compatible string
rather than the channel type, however the smd-rpm module uses rpmsg ID
instead. Thus if the smd-rpm is built as a module, it doesn't get
automatically loaded. Add generic compatible to such devices and fix
module's ID table.

Module loading worked before the commit bcabe1e09135 ("soc: qcom:
smd-rpm: Match rpmsg channel instead of compatible"), because the driver
listed all compatible strings, but the mentioned commit changed ID
table. Revert the offending commit and add generic compatible strings
instead.

Changes in v2:
- Separate fix from the improvements (Krzysztof
- Split the qcom,glink-smd-rpm compat from the qcom,smd-rpm as they use
  different channels underneath.
- Link to v1: https://lore.kernel.org/r/20240729-fix-smd-rpm-v1-0-99a96133cc65@xxxxxxxxxx
