objections, please let us know.
===============
[ Upstream commit 34ff1bf4920471cff66775dc39537b15c5f0feff ]
The mask of sns_key_info1 suggests the upper nybble is being extracted
however the following shift of 8 bits is too large and always results in
0. Fix this by shifting only by 4 bits to correctly get the upper nybble.
Detected by CoverityScan, CID#142891 ("Operands don't affect result")
