>> WARNING: modpost: drivers/char/agp/parisc-agp.o(.text+0x7a0): Section mismatch in reference from the function init_module() to the function .init.text:parisc_agp_setup.isra.0()
The function init_module() references
the function __init parisc_agp_setup.isra.0().
This is often because init_module lacks a __init
annotation or the annotation of parisc_agp_setup.isra.0 is wrong.
