mtdblock_flush()
	-->write_cached_data()
		--->erase_write()
		     mtdblock: erase of region [0x40000, 0x20000] on "xxx" failed

Because mtdblock_flush() always returns 0,
even if write_cached_data() fails and data is not written to the device,
syscall_write() still returns success

I reworded a bit the commit log and also added a ' ' after 'mtd:' in
the title when applying.

Thanks,
Miquèl

Your revised commit log is more accurate and clearer, thanks for your correction
