[PATCH 12/68] 0 -> NULL, for arch/powerpc
From: Yoann Padioleau <hidden>
Date: 2007-07-27 09:50:29
When comparing a pointer, it's clearer to compare it to NULL than to 0. Here is an excerpt of the semantic patch: @@ expression *E; @@ E == - 0 + NULL @@ expression *E; @@ E != - 0 + NULL Signed-off-by: Yoann Padioleau <redacted> Cc: paulus@samba.org Cc: linuxppc-dev@ozlabs.org Cc: benh@kernel.crashing.org Cc: akpm@linux-foundation.org --- boot/prpmc2800.c | 2 +- kernel/btext.c | 8 ++++---- kernel/legacy_serial.c | 2 +- kernel/pci-common.c | 2 +- kernel/pci_32.c | 8 ++++---- kernel/prom.c | 4 ++-- kernel/setup_64.c | 4 ++-- kernel/signal_64.c | 4 ++-- mm/mmu_decl.h | 2 +- mm/pgtable_32.c | 4 ++-- mm/ppc_mmu_32.c | 2 +- mm/tlb_32.c | 12 ++++++------ platforms/52xx/lite5200.c | 2 +- platforms/83xx/mpc832x_mds.c | 2 +- platforms/83xx/mpc836x_mds.c | 2 +- platforms/85xx/mpc85xx_ads.c | 4 ++-- platforms/85xx/mpc85xx_cds.c | 4 ++-- platforms/86xx/mpc86xx_hpcn.c | 4 ++-- platforms/8xx/mpc86xads_setup.c | 4 ++-- platforms/8xx/mpc885ads_setup.c | 4 ++-- platforms/maple/pci.c | 2 +- platforms/maple/setup.c | 2 +- platforms/powermac/pci.c | 2 +- platforms/powermac/pfunc_core.c | 2 +- platforms/powermac/setup.c | 6 +++--- platforms/powermac/time.c | 6 +++--- platforms/pseries/setup.c | 2 +- sysdev/qe_lib/qe_io.c | 2 +- xmon/spu-dis.c | 18 +++++++++--------- xmon/xmon.c | 4 ++-- 30 files changed, 63 insertions(+), 63 deletions(-)
