Like the idea. Was on our list because it is damn convenient when testing on router with multiple devices. I would prefer to replace the existing brcmf_err() rather than introducing a new one and would like to do the same for brcmf_dbg(). However, not all call sites have a struct brcmf_pub instance available. Everywhere before completing brcmf_attach() that is.

I decided to try new macro because: 1) I was too lazy to convert all calls at once 2) I could stick to brcmf_err when struct brcmf_pub isn't available yet In theory we could pass NULL to dev_err, I'd result in something like: [ 14.746754] (NULL device *): brcmf_c_preinit_dcmds: Firmware version = wl0: Sep 18 2015 03:30:01 version 7.35.177.56 (r587209) FWID 01-6cb8e269 Unfortunately AFAIK it's not possible to handle brcmf_err(NULL "Foo\n"); calls while keeping brcmf_err a macro.
