Subject: [PATCH fixes 1/4] MIPS: mipsmtregs: Fix target register for MFTC0
Date: Sun, 16 Jun 2024 14:25:02 +0100	[thread overview]
Message-ID: <20240616-mips-mt-fixes-v1-1-83913e0e60fc@flygoat.com> (raw)
In-Reply-To: <20240616-mips-mt-fixes-v1-0-83913e0e60fc@flygoat.com>

Target register of mftc0 should be __res instead of $1, this is
a leftover from old .insn code.

Fixes: dd6d29a61489 ("MIPS: Implement microMIPS MT ASE helpers")
Cc: stable@vger.kernel.org
