From 80969836a7ddde326d3f289d234e9e2d9ed27272 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Sat, 9 Jun 2012 22:51:44 +0200 Subject: [PATCH] brcmfmac: expose sdio internal counters in debugfs The structure brcmf_sdio contains a number of counters that are useful for debugging. These were not available in user-space. This patch exposes them in debugfs under the filename 'counters'.
