Revision 4b3be6afa4ab8b3fdce39df68bad71f8b85164de authored by Julia Lawall on 17 October 2009, 06:33:22 UTC, committed by Takashi Iwai on 30 October 2009, 11:01:27 UTC
In pcm.c, if the NULL test on pcm is needed, then the dereference should be after the NULL test. In dummy.c and ali5451.c, the context of the calls to snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice, respectively cannot be NULL. A simplified version of the semantic match that detects this problem is as follows (http://coccinelle.lip6.fr/): // <smpl> @match exists@ expression x, E; identifier fld; @@ * x->fld ... when != \(x = E\|&x\) * x == NULL // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Takashi Iwai <tiwai@suse.de>

initramfs_data.S
/*
initramfs_data includes the compressed binary that is the
filesystem used for early user space.
Note: Older versions of "as" (prior to binutils 2.11.90.0.23
released on 2001-07-14) dit not support .incbin.
If you are forced to use older binutils than that then the
following trick can be applied to create the resulting binary:
ld -m elf_i386 --format binary --oformat elf32-i386 -r \
-T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o
ld -m elf_i386 -r -o built-in.o initramfs_data.o
initramfs_data.scr looks like this:
SECTIONS
{
.init.ramfs : { *(.data) }
}
The above example is for i386 - the parameters vary from architectures.
Eventually look up LDFLAGS_BLOB in an older version of the
arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced.
Using .incbin has the advantage over ld that the correct flags are set
in the ELF header, as required by certain architectures.
