crypto: inside-secure - Change swab to swab32
Browse files Browse the repository at this point in the history
[ Upstream commit 6645934 ]

The use of swab() is causing failures in 64-bit arch, as it
translates to __swab64() instead of the intended __swab32().
It eventually causes wrong results in xcbcmac & cmac algo.

Fixes: 78cf1c8 ("crypto: inside-secure - Move ipad/opad into safexcel_context")
