From: Arnd Bergmann <arnd@arndb.de>
The forward declaration was introduced with a prototype that does not match the function definition:
drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c:2166:13: error: conflicting types for 'xgbe_phy_perform_ratechange' due to enum/integer mismatch; have 'void(struct xgbe_prv_data *, enum xgbe_mb_cmd, enum xgbe_mb_subcmd)' [-Werror=enum-int-mismatch] 2166 | static void xgbe_phy_perform_ratechange(struct xgbe_prv_data *pdata, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/amd/xgbe/xgbe-phy-v2.c:391:13: note: previous declaration of 'xgbe_phy_perform_ratechange' with type 'void(struct xgbe_prv_data *, unsigned int, unsigned int)' 391 | static void xgbe_phy_perform_ratechange(struct xgbe_prv_data *pdata, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Ideally there should not be any forward declarations here, which would make it easier to show that there is no unbounded recursion. I tried fixing this but could not figure out how to avoid the recursive call.
As a hotfix, address only the broken prototype to fix the build problem instead.
