Subject: [PATCH] brcmfmac: Make sure CLM downloading is optional
Date: Mon, 15 Jan 2018 09:10:53 -0800 [thread overview]
Message-ID: <20180115171053.8802-1-bjorn.andersson@linaro.org> (raw)
The presence of a CLM file is described as optional, but missing the clm
blob causes the preinit to return unsuccessfully. Fix this by ignoring
the return value of the brcmf_c_process_clm_blob().
Also remove the extra debug print, as brcmf_c_process_clm_blob() already
did print a useful error message before returning.
Fixes: fdd0bd88ceae ("brcmfmac: add CLM download support")

This regression was introduced in v4.15-rc1, but I unfortunately didn't test
WiFi until now. Included a Cc to stable@ in case you choose to pick this up
after v4.15.
