Subject: [PATCH] riscv: Do not invoke early_init_dt_verify() twice
Date: Wed, 24 Mar 2021 23:03:12 +0800 [thread overview]
Message-ID: <20210324150312.20535-1-changbin.du@gmail.com> (raw)
In the setup_arch() of riscv, function early_init_dt_verify() has
been done by parse_dtb(). So no need to call it again. Just directly
invoke unflatten_device_tree().
