[PATCH 6.2 14/15] riscv: Do not set initial_boot_params to the linear address of the dtb

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Alexandre Ghiti <alexghiti@rivosinc.com>

commit f1581626071c8e37c58c5e8f0b4126b17172a211 upstream.

early_init_dt_verify() is already called in parse_dtb() and since the dtb
address does not change anymore (it is now in the fixmap region), no need
to reset initial_boot_params by calling early_init_dt_verify() again.
