From 108a4bee9db5d50e99b3aea349cbc987cc857b32 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Wed, 19 Sep 2012 22:21:07 +0200 Subject: brcmfmac: extend brcmf_term_iscan() to abort e-scan With the introduction of E-Scan there are two scan mechanisms in the driver. I-Scan was aborted on suspend and bringing down the device using brcmf_term_iscan(). The function has been renamed to brcmf_abort_scanning() and covers e-scan abort as well.
