Re: [U-Boot-Users] [PATCH] Fix use of "void *" for block dev read/write buffer pointers

My patch from April, 2nd, fixes this issue already. In my patch I decided to just cast the pointer back to ulong *, since I don't know if it is a good idea to increment a pointer to void *.

It's not part of the normal C standard, but gcc allows you to perform pointer math on a void *. It acts as is it were a "u8 *".

Remember, this code:

ulong *p; p++;

Has the same effect as:

void *p p += sizeof(ulong);
