From: Kalle Valo <kvalo@qca.qualcomm.com> To: <ath10k@lists.infradead.org> Cc: <linux-wireless@vger.kernel.org> Subject: [PATCH v2 1/4] ath10k: fetch firmware images in a loop Date: Fri, 10 Feb 2017 14:26:32 +0200 [thread overview] Message-ID: <148672959257.8556.14481306395015426550.stgit@potku.adurom.net> (raw) In-Reply-To: <148672934198.8556.5588600166627442652.stgit@potku.adurom.net> From: Erik Stromdahl <erik.stromdahl@gmail.com> 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.
