The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> Cc: Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/media/video/em28xx/em28xx-core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/media/video/em28xx/em28xx-core.c~drivers-media-video-em28xx-correct-use-of-and drivers/media/video/em28xx/em28xx-core.c --- a/drivers/media/video/em28xx/em28xx-core.c~drivers-media-video-em28xx-correct-use-of-and +++ a/drivers/media/video/em28xx/em28xx-core.c @@ -267,7 +267,7 @@ static int em28xx_write_ac97(struct em28 for (i = 0; i < 10; i++) { if ((ret = em28xx_read_reg(dev, AC97BUSY_REG)) < 0) return ret; - if (!((u8) ret) & 0x01) + if (!(((u8)ret) & 0x01)) return 0; msleep(5); } _ Patches currently in -mm which might be from julia@xxxxxxx are sound-use-bug_on.patch git-powerpc.patch git-hid.patch git-net.patch drivers-net-mv643xx_ethc-use-field_sizeof.patch git-ocfs2.patch fs-ocfs2-use-bug_on.patch drivers-block-viodasdc-use-field_sizeof.patch git-sh.patch usb-use-div_round_up.patch fs-affs-filec-use-bug_on.patch fbdev-use-div_round_up-or-roundup.patch fs-ext2-use-bug_on.patch fs-ext3-use-bug_on.patch fs-ext4-use-bug_on.patch drivers-acpi-asus_acpic-correct-use-of-and.patch drivers-char-isicomc-correct-use-of-and.patch drivers-isdn-correct-use-of-and.patch drivers-media-video-em28xx-correct-use-of-and.patch drivers-media-video-em28xx-correct-use-of-and-fix.patch drivers-net-wireless-iwlwifi-iwl-4965c-correct-use-of-and.patch drivers-serial-m32r_sioc-correct-use-of-and.patch fs-reiserfs-superc-correct-use-of-and.patch - To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
