[PATCH 2/4 v2] ath10k: better firmware loading error messages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ben Greear <greearb@xxxxxxxxxxxxxxx>

Let user know the name of the board file if it is not
found, and make it easier to determine the firmware
api being used.

Signed-off-by: Ben Greear <greearb@xxxxxxxxxxxxxxx>

v2:  Incorporate Kalle's suggestions and sample code.
