const? u8?
That is assigned to the "reg_offset" field of "struct ei_device"
(defined in the existing 8390.h) and that is:
u32 *reg_offset; /* Register mapping table */
So I can't change this.
Sure you can, you can assign a u8 to a u32 just fine.
It's not the value that's assigned, but a pointer to the table, so
for now it must be non-const u32 *.
The value fits in a u8. Might as well make it take
less data space. static const makes it read-only and
makes the compiler assign it just once instead of at
function invocation.
That needs changes to drivers/net/ethernet/8390/8390.h, and
also probably to some drivers that assign values to the array.
