From: Simon Horman <horms@xxxxxxxxxx> [ Upstream commit 020bfdc4ed94be472138c891bde4d14241cf00fd ] The correct format string for resource_size_t is %pa which acts on the address of the variable to be formatted [1]. [1] https://elixir.bootlin.com/linux/v6.11.3/source/Documentation/core-api/printk-formats.rst#L229 Introduced by commit 9d9326d3bc0e ("phy: Change mii_bus id field to a string") Flagged by gcc-14 as: drivers/net/ethernet/freescale/fec_mpc52xx_phy.c: In function 'mpc52xx_fec_mdio_probe': drivers/net/ethernet/freescale/fec_mpc52xx_phy.c:97:46: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Wformat=] 97 | snprintf(bus->id, MII_BUS_ID_SIZE, "%x", res.start); | ~^ ~~~~~~~~~ | | | | | resource_size_t {aka long long unsigned int} | unsigned int | %llx No functional change intended.
