Date: Wed, 23 Nov 2022 17:56:51 +0000 From: Conor Dooley <conor@...nel.org> To: Conor Dooley <conor.dooley@...rochip.com>, Jassi Brar <jassisinghbrar@...il.com> Cc: Daire McNamara <daire.mcnamara@...rochip.com>, linux-riscv@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH v3 1/2] soc: microchip: mpfs: handle failed system service requests From: Conor Dooley <conor.dooley@...rochip.com> If a service request fails, a non-zero, per-service error code will be set. Since the individual service drivers may wish to handle things differently, there's little point trying to do anything intelligent in the system controller driver. Let the caller know that things went wrong & leave the details of handling the error to it.
