From f454add47adb4133f297e1b7af07bf07b3983044 Mon Sep 17 00:00:00 2001 From: Raja Mani Date: Fri, 18 Mar 2016 11:44:21 +0200 Subject: [PATCH] ath10k: pass cal data location as an argument to ath10k_download_cal_{file|dt} Both ath10k_download_cal_file() and ath10k_download_cal_dt() uses hard coded file pointer (ar->cal_file) and device tree entry (qcom,ath10k-calibration-data) respectively to get calibration data content. There is a need to use those two functions in qca4019 calibration download sequence with different file pointer and device tree entry name. Modify those two functions to take cal data location as an argument. So that it can serve the purpose for other file pointer and device tree entry. This is just preparation before adding actual qca4019 calibration download sequence. No functional changes.
