Subject: [PATCH] riscv: vector: Fix output operands in context save
Date: Fri, 11 Sep 2026 21:42:17 +0200	[thread overview]
Message-ID: <20260911194218.3379486-1-aurelien@aurel32.net> (raw)

The __vstate_csr_save() inline assembly declares vcsr as an output
operand while the assembly only writes vstart, vtype, and vl. Remove it
as it is later saved by the C code.

Fixes: d863910eabaf ("riscv: vector: Support xtheadvector save/restore")
