mainline build failure on arm hosts

[Sudip Mukherjee]

Hi All,

The mainline kernel branch had been failing native build on arm hosts
for some weeks with the error:

drivers/crypto/caam/desc_constr.h: In function 'append_data.constprop':
./include/linux/fortify-string.h:57:29: error: argument 2 null where non-null expected [-Werror=nonnull]

cc1: all warnings being treated as errors


The commit 4f289826fee0 ("crypto: caam - Avoid GCC memset bug warning")
in linux-next fixes the build.
