phy: cadence-torrent: Constify struct cdns_torrent_vals_entry
'struct cdns_torrent_vals_entry' is not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security. On a x86_64, with allmodconfig: Before: ====== text data bss dec hex filename 85130 13214 16 98360 18038 drivers/phy/cadence/phy-cadence-torrent.o After: ===== text data bss dec hex filename 92234 6078 16 98328 18018 drivers/phy/cadence/phy-cadence-torrent.o Signed-off-by: Christophe JAILLET <[email protected]> Link: https://lore.kernel.org/r/dcc4e539999a840b3fd8f40fd8fd7523390232ac.1720718240.git.christophe.jaillet@wanadoo.fr Signed-off-by: Vinod Koul <[email protected]>
