[U-Boot] ext4write fails when writing into directory

Hi Stefan,

I have applied your set of 13 patches to fix ext4 into my 2016.07 u-boot tree. Endianess fixes as provided by Michael Walle are also applied. I'm building for a Freescale T1024RDB eval system.

When trying to write into a directory on MMC/SD card using ext4write, I get error message 'Invalid path'. Bi-secting the patches, I found that the error is introduced with your patch 6/13 "ext4: scan all directory blocks when looking up an entry", commit ID 11077d628b15869f59f05fb1e0dc8c94f026daae). Writing into a given directory on ext4 filesystem was basically working without that patch.

Writing into the root directory works without issues.

Do you have an idea?

Best regards, Thomas Schäfer
