Subject: [PATCH] brcmfmac: create debugfs files for bus-specific layer
|
|
|
|
Since we moved the drivers debugfs directory under ieee80211 debugfs the
|
|
debugfs entries need to be added after wiphy_register() has been called.
|
|
For most part that has been done accordingly, but for the debugfs entries
|
|
added by SDIO it was not and failed silently. This patch fixes that by
|
|
adding a bus-layer callback for it.
|
|
|
|
Fixes: 856d5a011c86 ("brcmfmac: allocate struct brcmf_pub instance using wiphy_new()")
