From 8868b12c0bb5e3d1be32353d54b5e84bb4b3bea1 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Mon, 17 Nov 2014 16:44:14 +0200 Subject: [PATCH] ath10k: add modpram 'skip_otp' to ignore empty otp error during BMI This patch would help bring up wifi interface with default board data in case of failures in otp download. It is useful for initial calibration.
