Hi, > From: Kees Cook [mailto:keescook@xxxxxxxxxxxx] > Subject: [PATCH] acpi: Fix format string type mistakes > > From: Emese Revfy <re.emese@xxxxxxxxx> > > This adds the missing __printf attribute which allows compile time > format string checking (and will be used by the coming initify gcc > plugin). Additionally, this fixes the warnings exposed by the attribute. > > Signed-off-by: Emese Revfy <re.emese@xxxxxxxxx> > [kees: split scsi/acpi, merged attr and fix, new commit messages] > Signed-off-by: Kees Cook <keescook@xxxxxxxxxxxx> > --- > drivers/acpi/acpica/dbhistry.c | 2 +- > drivers/acpi/acpica/dbinput.c | 10 ++--- > drivers/acpi/acpica/dbstats.c | 88 +++++++++++++++++++++--------------------- > drivers/acpi/acpica/utdebug.c | 2 +- > include/acpi/acpiosxf.h | 3 +- > 5 files changed, 53 insertions(+), 52 deletions(-) > > diff --git a/drivers/acpi/acpica/dbhistry.c b/drivers/acpi/acpica/dbhistry.c > index 46bd65d38df9..ec9da4830f6a 100644 > --- a/drivers/acpi/acpica/dbhistry.c > +++ b/drivers/acpi/acpica/dbhistry.c > @@ -155,7 +155,7 @@ void acpi_db_display_history(void) > > for (i = 0;
