#     crypto: inside-secure - do not use memset on MMIO
#     
#     This patch fixes the Inside Secure driver which uses a memtset() call to
#     set an MMIO area from the cryptographic engine to 0. This is wrong as
#     memset() isn't guaranteed to work on MMIO for many reasons. This led to
#     kernel paging request panics in certain cases. Use memset_io() instead.
#     
#     Fixes: 1b44c5a60c13 ("crypto: inside-secure - add SafeXcel EIP197 crypto engine driver")
