wifi: ath9k: fix printk specifier
[ Upstream commit 061115fbfb2ce5870c9a004d68dc63138c07c782 ]
Smatch reports:
ath_pci_probe() warn: argument 4 to %lx specifier is cast from pointer
ath_ahb_probe() warn: argument 4 to %lx specifier is cast from pointer
Fix it by modifying %lx to %p in the printk format string.
Note that with this change, the pointer address will be printed as a
hashed value by default. This is appropriate because the kernel
should not leak kernel pointers to user space in an informational
message. If someone wants to see the real address for debugging
purposes, this can be achieved with the no_hash_pointers kernel option.
