In a SoC based solution, it would be useful to know the versions of the
various binary firmware blobs the system is running on. On a QCOM based
SoC, this info can be obtained from socinfo debugfs infrastructure. For
this to work, respective subsystem drivers have to export the firmware
version information to an SMEM based version information table.
Having firmware version information at one place will help quickly
figure out the firmware versions of various subsystems on the device
instead of going through builds/logs in an event of a system crash.
Fill WLAN firmware version information in SMEM version table to be
printed as part of socinfo debugfs infrastructure on a Qualcomm based
SoC.
This change is applicable only for WCN399X targets.

should you s/128/MAX_BUILD_ID_LEN/ since that is what is used to size
qmi->fw_build_id?
or alternately have the caller pass fw_build_id length as a separate param?

BTW Youghandhar, your quotes were broken in this mail so your reply was
difficult to find. See here:
https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
If you are using Outlook, I recommend switching to an application which
respects standards more :) For example, some people seem to be happy
with Thunderbird.

Thank you so much for your suggestion. I will address it.
Currently I am using Thunderbird.
