PCI: ls-gen4: Make struct mobiveil_rp_ops constant
The struct mobiveil_rp_ops is not modified in this driver. Thus, make this struct constant, which also moves data to a read-only section decreasing object size and also improving overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 4446 336 32 4814 12ce drivers/pci/controller/mobiveil/pcie-layerscape-gen4.o After: ===== text data bss dec hex filename 4454 328 32 4814 12ce drivers/pci/controller/mobiveil/pcie-layerscape-gen4.o [kwilczynski: commit log] Link: https://lore.kernel.org/linux-pci/189fd881cc8fd80220e74e91820e12cf3a5be114.1719260294.git.christophe.jaillet@wanadoo.fr Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Krzysztof Wilczyński <kwilczynski@kernel.org>
