Subject: [PATCH] backports: only add net_get_random_once() when not available
|
||
|
|
|
||
|
|
Upstream commit: d787b3dd3b4fcb5f40eb6532163dc3abdca4fd45
|
||
|
|
|
||
|
|
net_get_random_once() was added unconditionally also when the kernel we
|
||
|
|
are compiling against already provided this function, this patch checks
|
||
|
|
that first.
