[PATCH 5.12 144/173] tools/bootconfig: Fix error return code in apply_xbc()

[Greg Kroah-Hartman]

From: Zhen Lei <thunder.leizhen@xxxxxxxxxx>

commit e8ba0b2b64126381643bb50df3556b139a60545a upstream.

Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.
