Subject: [PATCH] net: mscc: ocelot: remove incompatible prototypes

From: Arnd Bergmann <[email protected]>

The types for the register argument changed recently, but there are
still incompatible prototypes that got left behind, and gcc-13 warns
about these:

In file included from drivers/net/ethernet/mscc/ocelot.c:13:
drivers/net/ethernet/mscc/ocelot.h:97:5: error: conflicting types for 'ocelot_port_readl' due to enum/integer mismatch; have 'u32(struct ocelot_port *, u32)' {aka 'unsigned int(struct ocelot_port *, unsigned int)'} [-Werror=enum-int-mismatch]
97 | u32 ocelot_port_readl(struct ocelot_port *port, u32 reg);
| ^~~~~~~~~~~~~~~~~

Just remove the two prototypes, and rely on the copy in the global
header.

Fixes: 9ecd05794b8d ("net: mscc: ocelot: strengthen type of "u32 reg" in I/O accessors")

Interesting, I didn't even realize we had these duplicated there. Thanks.
FWIW, they were duplicated in commit 5e2563650232 ("net: mscc: ocelot:
publish structure definitions to include/soc/mscc/ocelot.h") and haven't
bothered anybody since then.
