remoteproc updates for v6.5
The bulk of these patches relates to the moving to a void-returning remove callback. The i.MX HiFi remoteproc driver gets its pm_ops helpers updated to resolve build warnings about "defined but not used" variables in certain configurations. The ST STM32 remoteproc driver is extended to allow using a SCMI reset controller to hold boot, and has an error message corrected. The Qualcomm Q6V5 PAS driver gains a missing "static" qualifier on adsp_segment_dump(). -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmSjLeMVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FrC0P/jRxXCckwudaZFEQW3LTr8QDI/zV +ZkVBV9VUfjV64mY0Z6dAihXcONVYCNhKXX+6h+I/nxUfAqAJY7wbQBDmB/C7EL0 qm185BBHNr8XmxezwmttKpeiCibcRoLbSCOeJXjXbOU3op/h7zTu6zLE2gLPWvWM s+x784cbiK5W/IY8DWoSHKW5XXMjgTta8pk8VhovnB/EokHjdbEHXQgpn/HVogvk ErczPWli8+bmzlAwd5RUNUW6q/Lnx3ffjC5dsVhlqK0iGNIu6fa0YUk35Uc7ig09 0D2iZBqZLff/2WTW+PMHfdNl6dfzcLBLgoDpnFwOX2QO17qjKHTQfAwDshJkhKw6 9BiJifXaVX2vrBCd7REUrAeHmzIbgO+yCnKFr1UyLmbj0x/DXQLCQHrkPXycKgKi Z9ujdJC7XsFyn1DSgxNSSWSpDhJOuMX77Umi/ASRWPha15H3YlOjqXV/Vaoy0iPg E7iCL2dd11X9s/LXp16ahcAgb7c6vEXclWm1CsTQzhMDLMmVBysMa/AWg8Gtq4hW pxCwsGWG7CTTAE2/E7N6AX/caNRs2Z++b6MLRVrIvvokgnk2Ofhqlyn71r7FstlV uBWUM9BszeIzG6NYAKWjRo036tVgTWnMWsy+i5uSOEUD6JsaMm7TnjVEOAtz1cQE VWbln8J7plG5ly6g =9t2a -----END PGP SIGNATURE----- Merge tag 'rproc-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "The bulk of these patches relates to the moving to a void-returning remove callback.
