Subject: [PATCH] arm64: crypto: fix typo in aes_sub()
Clang's integrated assembler can't parse "v0.4s[0]" argument of the UMOV
instruction. And, as per ARM ARM, this is incorrect usage:
UMOV <Wd>, <Vn>.<Ts>[<index>]
...
<Ts> For the 32-bit variant: is an element size specifier, encoded in
the "imm5" field. It can have the following values:
B when imm5 = xxxx1
H when imm5 = xxx10
S when imm5 = xx100
