Subject: package/mke2img: specifying zero inodes means auto
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9b5df8f2c3c4e0aa4bca8af0cb05594063725d46;p=buildroot.git

package/mke2img: specifying zero inodes means auto

Currently, leaving the number of inodes to be autocalculated requires
the user to not specify the -i option at all.

Also accept zero as meaning auto; this will help simplify the ext2.mk
code a little bit.
