Subject: [PATCH] brcmfmac: Fix oops when SDIO device is removed.
|
|
|
|
On removal of SDIO card both functions of card will be getting
|
|
a remove call. When the first is hanging in ctrl frame xmit then
|
|
the second will cause oops. This patch fixes the xmit ctrl
|
|
handling in case of serious errors and also limits the handling
|
|
for remove to function 1 only.
