[OE-core] simplest command to display which layers are applying the same patch?

[rpjday at crashcourse.ca]

   just got from colleague a miniscule snippet of build output:

ERROR: openssl-1.0.2u-r0 do_patch: Command Error: 'quilt --quiltrc ...  
snip ...
Output: Patch Use-SHA256-not-MD5-as-default-digest.patch is already  
applied; check your series file

the problem seems obvious ... more than one layer being pulled
into the build is trying to apply the same patch to that version
of openssl.

i don't have access to that build system, but i'm not surprised
as it appears that at least three layers (oe-core, vendor, and
wind river linux fixes layer) all supply that very patch.

what is the simplest command from way back in "morty" that
could display something as clear as, "layer A already applied
this patch, now layer B is trying to apply it as well?"

if it's in the log file, i can just point the person at that,
short of getting access to the build system and finding it
myself.  thank you kindly.
