Commit Message

Christophe JAILLET Nov. 15, 2024, 9:12 p.m. UTC 
'struct pci_device_id' is not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  36999	   2451	     88	  39538	   9a72	drivers/message/fusion/mptfc.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  37415	   2043	     88	  39546	   9a7a	drivers/message/fusion/mptfc.o

Compile tested-only.
