[ Upstream commit 45fe45fada261e1e83fce2a07fa22835aec1cf0a ]
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/print...
Introduced by commit 9d9326d3bc0e ("phy: Change mii_bus id field to a string")
Flagged by gcc-14 as:
drivers/net/ethernet/freescale/fs_enet/mii-bitbang.c: In function 'fs_mii_bitbang_init': drivers/net/ethernet/freescale/fs_enet/mii-bitbang.c:126:46: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Wformat=] 126 | 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. Compile tested only.
