6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Damien Le Moal <dlemoal@xxxxxxxxxx>
[ Upstream commit fd46bc0e0bb3c6607363bd23f2b3c2a73dc75d66 ]
When compiling the Rockchip endpoint driver with -W=1, the following
warnings can be seen in the output:
drivers/pci/controller/pcie-rockchip-ep.c:59: warning: Function parameter or struct member 'perst_irq' not described in 'rockchip_pcie_ep'
drivers/pci/controller/pcie-rockchip-ep.c:59: warning: Function parameter or struct member 'perst_asserted' not described in 'rockchip_pcie_ep'
drivers/pci/controller/pcie-rockchip-ep.c:59: warning: Function parameter or struct member 'link_up' not described in 'rockchip_pcie_ep'
drivers/pci/controller/pcie-rockchip-ep.c:59: warning: Function parameter or struct member 'link_training' not described in 'rockchip_pcie_ep'
Fix these warnings by adding the missing field descriptions in
struct rockchip_pcie_ep kernel-doc comment.
Fixes: a7137cbf6bd5 ("PCI: rockchip-ep: Handle PERST# signal in EP mode")
Fixes: bd6e61df4b2e ("PCI: rockchip-ep: Improve link training")
