Subject: [RFC PATCH 04/11] lib: sbi_hsm: Move misplaced comment
Date: Fri, 6 Jan 2023 12:22:02 +0100 [thread overview]
Message-ID: <20230106112209.441825-5-ajones@ventanamicro.com> (raw)
In-Reply-To: <20230106112209.441825-1-ajones@ventanamicro.com>
While non-retentive suspend is not allowed for M-mode, the comment
at the top of sbi_hsm_hart_suspend() implied suspend wasn't allowed
for M-mode at all. Move the comment above the mode check which is
inside a suspend type is non-retentive check.
