Linus Torvalds [Sat, 3 Jan 2009 19:46:17 +0000 (11:46 -0800)]
Make %p print '(null)' for NULL pointers

Before, when we only ever printed out the pointer value itself, a NULL
pointer would never cause issues and might as well be printed out as
just its numeric value.

However, with the extended %p formats, especially %pR, we might validly
want to print out resources for debugging.  And sometimes they don't
even exist, and the resource pointer is just NULL.  Print it out as
such, rather than oopsing.

This is a more generic version of a patch done by Trent Piepho (catching
all %p cases rather than just %pR, and using "(null)" instead of
"[NULL]" to match glibc).

15 years agoV4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by zero error
Michael Krufky [Fri, 2 Jan 2009 18:55:29 +0000 (15:55 -0300)]
V4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by zero error

A user reported the following OOPS with his pcHDTV HD5500 card, which
uses a cx88 PCI bridge with a LG-TDVS-H06xF frontend module, made up
of a TUA6034 tuner, TDA988x IF demod, and LG DT3303 ATSC/QAM demod.

Somehow, tuner-core gets loaded before the digital driver configures
the tuner, and tuner-core somehow incorrectly sets the tuner type to
LG NTSC (TAPE series) instead of LG TDVS-H06xF.  This tuner type does
not have the tuning stepsize defined, so an OOPS occurs during the
digital tune function.

We still dont know how the type gets set incorrectly in the first place.
The user has a tainted kernel with a binary nividia module, which COULD
have something to do with this, but it's hard to say for sure.

Nevertheless, to avoid this division by zero, we should check that
stepsize is defined.  If stepsize is not defined, print an error and
bail out on the tune request.

special cases in the probing code.

This structure uses the __u32 types for some of its members, which leads
to the following compile error:

    $ cc -I.../include -c X.c

It seems that these types are appropriate for this structure as it is
to be exposed to userspace.  These types are available via linux/types.h
so move the include of that outside the __KERNEL__ section.
