Subject: [PATCH] blscfg: return NULL instead of a zero-length array in
|
|
bls_make_list()
|
|
|
|
The bls_make_list() function returns a list of all the values for a given
|
|
key and if there is none a NULL pointer should be returned. But currently
|
|
is returnin a zero-length array instead.
|
|
|
|
This makes the callers to wrongly assume that there are values for a key
|
|
and populate wrong menu entries. For example menu entries are populated
|
|
with an initrd command even if there is no initrd fiel in the BLS file.
|
|

Resolves: rhbz#1806022
