[PATCH 5.4 008/434] net: phy: ensure that phy IDs are correctly typed

[Greg Kroah-Hartman]

From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>

[ Upstream commit 7d49a32a66d2215c5b3bf9bc67c9036ea9904111 ]

PHY IDs are 32-bit unsigned quantities. Ensure that they are always
treated as such, and not passed around as "int"s.

Fixes: 13d0ab6750b2 ("net: phy: check return code when requesting PHY driver module")
