Subject: [PATCH] brcmfmac: pass bus to the __brcmf_err() in pcie.c
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
|
|
It makes error messages more meaningful and is important for debugging
|
|
errors/bugs on systems with multiple brcmfmac supported devices.
|
|
|
|
All bus files should follow & get updated similarly (soon).
