A compile with sparse (make C=1) shows a couple of warnings:
like:
chzcrypt.c:36:3: warning: symbol 'l' was not declared.
Should it be static?
lszcrypt.c: In function 'show_device':
lszcrypt.c:556:9: warning: 'card' may be used uninitialized
[-Wmaybe-uninitialized]
Fix those warnings.

When many domains per card are available, then the results of the SCDMD
CHSC call may not fit into the output area, and a partial result is
returned. The further results must be retrieved with another CHSC call.
Fix the code to pass the correct next-domain to the subsequent CHSC call
of a partial response. Otherwise the same set of domains 1 to n are
retrieved again, resulting in an infinite loop, because this will always
produce a partial result.

Dependent on kernel config option CHSC_SCH the device node /dev/chsc may
exist per default or not. In case the kernel is built with CHSC_SCH=M,
then the device driver is built as separate kernel module, and must
therefore be loaded using modprobe chsc_sch to make device node /dev/chsc
available.

The zcryptstats tool displays usage statistics of IBM Crypto Express
adapters. It obtains cryptographic performance measurement data
periodically and displays the data for each cryptographic device for
each interval. A cryptographic device can be either a card device or
a queue device (APQN).
