This patchset make some clean up:
patch 1:remove useless parameters
patch 4:replace 'sprintf' with 'scnprintf'
patch 7:fix static check warning
and the rest patch fix some coding style
Resend this patch series because it depends on
https://patchwork.kernel.org/cover/11715927/
(crypto: hisilicon/qm - misc fixes).
Now the patch series(crypto: hisilicon/qm - misc fixes) has been applied.
So this patch series will apply against cryptodev.
Shukun Tan (1):
crypto: hisilicon/zip - modify debugfs interface parameters
Yang Shen (9):
crypto: hisilicon/zip - remove some useless parameters
crypto: hisilicon/zip - unify naming style for functions and macros
crypto: hisilicon/zip - replace 'sprintf' with 'scnprintf'
crypto: hisilicon/zip - use a enum parameter instead of some macros
crypto: hisilicon/zip - add print for error branch
crypto: hisilicon/zip - fix static check warning
crypto: hisilicon/zip - move some private macros from 'zip.h' to
'zip_crypto.c'
crypto: hisilicon/zip - supplement some comments
crypto: hisilicon/zip - fix some coding styles
