Subject: [PATCH] brcmfmac: Remove brcmf_sdiod_request_data()
|
||||
|
||||
This function is obfuscating how IO works on this chip. Remove it
|
||||
and push its logic into brcmf_sdiod_reg_{read,write}().
|
||||
|
||||
Handling of -ENOMEDIUM is altered, but as that's pretty much broken anyway
|
||||
we can ignore that.
