With the reimplementation of probe_kernel_address() in commit
ecc83243e1d4 ("uaccess: reimplement probe_kernel_address() using
probe_kernel_read()"), the explication of the cast for the addr
parameter has been dropped. So we have to explicitly cast the
regs->nip to void * when passing it to probe_kernel_address() in
order to fix the following build error:
arch/powerpc/sysdev/fsl_pci.c: In function 'fsl_pci_mcheck_exception':
arch/powerpc/sysdev/fsl_pci.c:1002:4: error: passing argument 2 of
'probe_kernel_read' makes pointer from integer without a cast [-Werror]
ret = probe_kernel_address(regs->nip, inst);
