Subject: [PATCHv2 0/2] Avoid firmware warning in imx-sdma

Hi,

I grabbed the first patch from patchwork from an 2017 patch series. As far as I
could see, their usecase vanished due to switching to sync FW API (that already
supports NOWARN). This series fixes a kernel warning in imx-sdma driver, which
works fine with ROM firmware (and already prints an info message about ROM
firmware being used due to missing firmware file). This has been tested on
arch/arm/boot/dts/imx53-ppd.dts.

Changes since PATCHv2:
 * Provide request_firmware_nowait_nowarn instead of generic function with
   flags as suggested by Luis [0]
