openwrt/target/linux/layerscape/patches-5.4/801-audio-0005-Revert-ASoC-fsl_sai-Add-support-for-SAI-new-version.patch
Adrian Schmutzler 83b1e40561 kernel: bump 5.4 to 5.4.59 
Removed since added upstream:
  bcm27xx:
    950-0428-staging-vchiq_arm-Add-a-matching-unregister-call.patch
  lantiq:
    0800-spi-lantiq-ssc-Fix-warning-by-using-WQ_MEM_RECLAI.patch

Manually adjusted patches:
  layerscape:
    801-audio-0005-Revert-ASoC-fsl_sai-Add-support-for-SAI-new-version.patch

Build-tested: ath79/generic, ramips, lantiq/xrx200, lantiq/xway,
   mvebu/cortexa9, sunxi/a53
Run-tested: ipq806x (R7800), layerscape (LS1012A-FRDM, LS1046A-RDB)

Building on layerscape is only possible with workaround from PR #3179.
