mtd: remove the warning about read-only caused by size vs. block boundary mismatch
Since the kernel/rootfs split handling was modified 2 years ago by r37283 (
https://dev.openwrt.org/changeset/37283 ) and by the subsequent checkins,
users have seen rather scary mtd errors in the log at every boot. The message
ends "-- forcing read-only", which looks a bit error-like. That error has
been mentioned in some forum threads, when users have noticed this message
instead of some actual error.
[ 2.940000] 0x000000070000-0x000000ff0000 : "firmware"
[ 2.970000] 2 netgear-fw partitions found on MTD device firmware
[ 2.970000] 0x000000070000-0x000000188440 : "kernel"
[ 2.980000] mtd: partition "kernel" must either start or end on erase
block boundary or be smaller than an erase block -- forcing read-only
[ 2.990000] 0x000000188440-0x000000ff0000 : "rootfs"
The patch removes the rather useless warning message.
