From 4d1a4f16c96d3f4cf6afd92ca3ffb4d2c24875e1 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Thu, 20 Mar 2014 10:18:02 +0100 Subject: [PATCH] brcmfmac: only show error message when brcmf_sdiod_regrw_helper() fails In the function brcmf_sdiod_request_data() an error message is logged, but the calling function retries it. This patch will only log an error message when retry limit is reached. The low-level error is still logged by a SDIO debug message.
