Subject: [PATCH] net: ethernet: ti: am65-cpsw: fix CONFIG_PM #ifdef

From: Arnd Bergmann <[email protected]>

The #ifdef check is incorrect and leads to a warning:

drivers/net/ethernet/ti/am65-cpsw-nuss.c:1679:13: error: 'am65_cpsw_nuss_remove_rx_chns' defined but not used [-Werror=unused-function]
1679 | static void am65_cpsw_nuss_remove_rx_chns(void *data)

It's better to remove the #ifdef here and use the modern
SYSTEM_SLEEP_PM_OPS() macro instead.

Fixes: 24bc19b05f1f ("net: ethernet: ti: am65-cpsw: Add suspend/resume support")

Looks good to me.
