The s3c24xx_init_intc() returns an error pointer upon failure, not NULL.
let's add an error pointer check in s3c24xx_handle_irq.

Fixes: 1f629b7a3ced ("ARM: S3C24XX: transform irq handling into a declarative form")

Please use scripts/get_maintainers.pl to get list of mailing lists to
CC. You skipped two - arm and LKML.

Thanks for the patch but it does not look entirely correct.

For platform based machines, neither ERR nor NULL can happen here.
The s3c24xx_handle_irq() will be set as IRQ handler iff this succeeds:
    s3c_intc[0] = s3c24xx_init_intc()

If this fails, the next calls to s3c24xx_init_intc() won't be executed.

For DT machine, s3c_init_intc_of() could set the IRQ handler without
setting s3c_intc[0] only if it was called with num_ctrl=0. There is no
such code path, so again the s3c_intc[0] will have a valid pointer if
set_handle_irq() is called.

Therefore in s3c24xx_handle_irq(), the s3c_intc[0] is always something.

The code can be simplified by removing if(), if we really wanted and
were sure about it.

For the non-DT case, this seems ugly but proper solution. The
s3c_intc[2] could be NULL (not set at all) or set as ERR (if
s3c24xx_init_intc() fails).

In fact, I didn't study his underlying logic in depth, but found that
this place was not particularly perfect based on the return value of the
function, because I happened to encounter a similar problem elsewhere.
