[REGRESSION] firmware: qcom: scm: smc: switch to using the SCM allocator

Thanks for looking into this! Please let me know how I can help!


I've been building the driver into the kernel I believe. Here's the 
relevant line in the config:

$ rg -i "scm"
samsung/expressatt/linux.defconfig
1615:# CONFIG_ARM_SCMI_PROTOCOL is not set
1627:CONFIG_QCOM_SCM=y
1628:# CONFIG_QCOM_SCM_DOWNLOAD_MODE_DEFAULT is not set


It seems like the scm driver is being probed:

~ # dmesg | grep scm
[    0.066438] qcom_scm: convention: smc legacy
[    0.362543] bus: 'platform': add driver qcom_scm


Also here is the complete dmesg output (Had to paste in pastebin as it 
made the email bigger than 100 KB):
