volatile void * pointer conversion

[Josef Angermeier <sijoange@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hello

Is there any way to cast a volatile void pointer to e.g. a char pointer,
without getting a warning from gcc ?

Here is the warning:

pci.c:665: warning: cast discards qualifiers from pointer target type


example code:

extern int
pci_copyrom(volatile void * p)
{
	unsigned char * romp;

	romp = (unsigned char *) p;


thanks in advance
