Subject: hppfs: fix the return value of get_inode()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=91312c53aff4c9863dca6080182091dc5c5824c6;p=openwrt%2Fstaging%2Fblogic.git

hppfs: fix the return value of get_inode()

In case of error, the function get_inode() returns ERR_PTR().
But the users hppfs_lookup() and hppfs_fill_super() use NULL
test for check the return value, not IS_ERR(), so we'd better
change the return value of get_inode() to NULL instead of
ERR_PTR().

dpatch engine is used to generated this patch.
