Commit 13d31894b3c459805303325aa5b91f9cd4ed70bc

Authored by Pavel Emelianov
Committed by Linus Torvalds
1 parent a6a8bd6d28
Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

Make crypto API use seq_list_xxx helpers 

Simple and stupid - just use the same code from another place in the kernel.
