Subject: ext4: error handling fix in ext4_ext_convert_to_initialized()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f85b287a01237857a50c93868231f7e831581a27;p=openwrt%2Fstaging%2Fblogic.git

ext4: error handling fix in ext4_ext_convert_to_initialized()

When allocated is unsigned it breaks the error handling at the end
of the function when we call:
	allocated = ext4_split_extent(...);
	if (allocated < 0)
		err = allocated;

I've made it a signed int instead of unsigned.
