From 1c61bedc0a725f0b019a70bba07cb2cf05c4ae2a Mon Sep 17 00:00:00 2001 From: Erik Stromdahl Date: Mon, 13 Feb 2017 12:38:40 +0200 Subject: ath10k: fetch firmware images in a loop To make it easier to handle minimum and maximum firmware API numbers convert the firmware fetch functionality to a loop. If no firmware image is found print an error with minimum and maximum API numbers and the name of firmware directory. This is needed when we switch to using request_firmware_direct() which doesn't print any errors anymore. Also add a new function for creating the fw file name dynamically which makes it easier to add new bus support, for example SDIO and USB, later.
