Subject: [PATCH 102/482] Remove nested functions from PCI iterators.
* grub-core/bus/pci.c (grub_pci_iterate): Add hook_data argument,
passed to hook. Update all callers to pass appropriate hook data.
* grub-core/bus/emu/pci.c (grub_pci_iterate): Likewise.
* include/grub/pci.h (grub_pci_iteratefunc_t): Add data argument.
Remove NESTED_FUNC_ATTR from here and from all users.
(grub_pci_iterate): Update prototype.
* grub-core/bus/cs5536.c (grub_cs5536_find: hook): Make static
instead of nested. Rename to ...
(grub_cs5536_find_iter): ... this.
* grub-core/kern/efi/mm.c (stop_broadcom: find_card): Likewise.
* grub-core/kern/mips/loongson/init.c (init_pci: set_card):
Likewise.
* grub-core/kern/vga_init.c (grub_qemu_init_cirrus: find_card):
Likewise.
* grub-core/video/bochs.c (grub_video_bochs_setup: find_card):

* grub-core/video/cirrus.c (grub_video_cirrus_setup: find_card):

find_card): Likewise.
* grub-core/video/sm712.c (grub_video_sm712_setup: find_card):
Likewise.
