Subject: [PATCH v2 2/4] crypto: ccp - Declare PSP dead if PSP_CMD_TEE_RING_INIT fails
Date: Thu, 11 Dec 2025 15:28:45 -0600 [thread overview]
Message-ID: <20251211212847.11980-3-superm1@kernel.org> (raw)
In-Reply-To: <20251211212847.11980-1-superm1@kernel.org>
tee_init_ring() only declares PSP dead if the command times out.
If there is any other failure it is still considered fatal though.
Set psp_dead for other failures as well.
