hw_random driver unsafe endianness assumption

I was looking over some uses of the SMCCC TRNG interface and came across the hw_random driver. In copy_from_registers() from drivers/char/hw_random/arm_smccc_trng.c, the trailing entropy is copied out of a1 with memcpy(&buf[copied], &res->a1, chunk). That appears to make an unsafe assumption about endianness? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
