The build of drivers/staging/gpib/hp_82341 driver was failing
with:

ERROR: modpost: "isapnp_read_byte"
[drivers/staging/gpib/hp_82341/hp_82341.ko] undefined!

because the symbol was not exported for modules.

There were no errors building with allyesconfig

The symbol was removed by
Link: https://lore.kernel.org/all/20051030202734.GN4180@stusta.de/
because it was no longer used by any mainline modules.

Export the symbol again.
