[PATCH] Bluetooth: Populate hci_set_hw_info for Intel and Realtek

From: Archie Pusaka
Date: Mon Apr 22 2024 - 03:28:03 EST


From: Archie Pusaka <apusaka@xxxxxxxxxxxx>

The hardware information surfaced via debugfs might be usable by the
userspace to set some configuration knobs. This patch sets the hw_info
for Intel and Realtek chipsets.
