[...] This commit was intended to allow support for 256 cards with any number of partitions: commit a26eba614afff0e39594101bcb73014a9a22fb33 Author: Ben Hutchings Date:=C2=A0=C2=A0=C2=A0Thu Nov 6 03:35:09 2014 +0000 =C2=A0=C2=A0=C2=A0=C2=A0mmc: block: Increase max_devices I don't think the new patch is sufficient or necessary to increase the limit further.
