It just has been merged into arm-soc/arm/drivers a day too late: $ git log --pretty=oneline arm-soc/arm/drivers | head -n2 25da503ecce8f523c1c1c678659cb484d3bcd73f Merge tag 'reset-for-v5.14-2' of git://git.pengutronix.de/pza/linux into arm/drivers 1eb5f83ee936de6a69b2bcee95088a6e0ab7c202 Merge tag 'memory-controller-drv-tegra-5.14-2' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers memory-controller-drv-tegra-5.14-2 contains the offending commit 56ebc9b0d77e, which depends on commit 48a74b1147f7 in reset-for-v5.14-2. Is the arm-soc/arm/drivers branch still mutable? IIUC this could be fixed by reordering the two merges. regards Philipp
