Subject: generic: 6.1: fix uImage.FIT partitions on mtdblock and ubiblock
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e386b279fdab758f75160636bca5385dae202aee;p=openwrt%2Fopenwrt.git

generic: 6.1: fix uImage.FIT partitions on mtdblock and ubiblock

When refreshing the hack patches for Linux 6.1 the part of the uImage.FIT
partition parser patch which takes care of allowing mtdblock and ubiblock
devices to have partitions has been dropped, supposedly by accident.
Re-add a that part to the patch, so devices using a uImage.FIT filesystem
sub-image as rootfs can work with Linux 6.1.

Fixes: 19a246bb65 ("generic: 6.1: manually refresh hack patches")
