[PATCH 1/2] ath10k: add helper method to grab debug stats.

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

 



From: Ben Greear <greearb@xxxxxxxxxxxxxxx>

It can be nice to update the firmware's stats while
debugging other bits of the driver, so add helper method
to do this.
