From ee410de890cdf8fc94f6235dd9ef323a101511ab Mon Sep 17 00:00:00 2001 From: Harald Freudenberger Date: Thu, 4 Oct 2018 15:30:24 +0200 Subject: s390/zcrypt: zcrypt device driver cleanup Some cleanup in the s390 zcrypt device driver: - Removed fragments of pcixx crypto card code. This code can't be reached anymore because the hardware detection function does not recognize crypto cards < CEX2 since commit f56545430736 ("s390/zcrypt: Introduce QACT support for AP bus devices.") - Rename of some files and driver names which where still reflecting pcixx support to cex2a/cex2c. - Removed all the zcrypt version strings in the file headers. There is only one place left - the zcrypt.h header file is now the only place for zcrypt device driver version info. - Zcrypt version pump up from 2.2.0 to 2.2.1.
