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] [0] https://lore.kernel.org/lkml/20180628031332.GE21242@xxxxxxxxxxxxx/ -- Sebastian Sebastian Reichel (2): firmware: add request_firmware_nowait_nowarn function dmaengine: imx-sdma: request firmware with FW_OPT_NO_WARN drivers/base/firmware_loader/main.c | 40 ++++++++++++++++++++++++----- drivers/dma/imx-sdma.c | 10 +++----- include/linux/firmware.h | 12 +++++++++ 3 files changed, 48 insertions(+), 14 deletions(-) -- 2.18.0 -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
