From 7dc5fe0814c35ec4e7d2e8fa30abab72e0e6a172 Mon Sep 17 00:00:00 2001 From: Amit Pundir Date: Mon, 16 Apr 2018 12:10:24 +0530 Subject: [PATCH] Bluetooth: hci_qca: Avoid missing rampatch failure with userspace fw loader AOSP use userspace firmware loader to load firmwares, which will return -EAGAIN in case qca/rampatch_00440302.bin is not found. Since there is no rampatch for dragonboard820c QCA controller revision, just make it work as is.
