From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx> Ingo, Boris is on vacation so sending this through you. This is just a resend of the v2 series. The issue here was the WARN() splat on built-in kernels due to ivtv's funky probe which will trigger even if you don't have any ivtv hardware. I've moved this to only trigger upon a device detection. We also spoke about not doing any of this and and letting it silently fail for these drivers but since this is only for two drivers and the ipath diver will be removed only the ivtv driver would be left with this work around. I'd like to enforce the semantics for usage of arch_phys_wc_add() with ioremap_wc() and making an exception just for ivtv does not seem worth the gains of having strong semantics. After all the ioremap_wc() + arch_phys_wc_add() are in I'll then try to add an SmPL rule check to enforce semantics on the ioremap_wc() + arch_phys_wc_add() API. Hope is that maintainers can vet new code for its correct usage in the future with 'make coccicheck M=path' on their subsystems. For your reference we discussed this and I mentioned my semantics preference and you were OK with this [0] so just resending this series as it fell through the cracks as Boris is on vacation now. Although the WARN() --> pr_warn() change is not techically needed for ipath, we make both checks consistent and less chatty. Since the ivtv change is splattering all v4.2 kernels that patch may be worthy for v4.2 inclusion. I did not peg the Cc: stable tag so leave this up to you to decide. Please let me know if this is OK or if there are any other oustandind issues. [0] http://lkml.kernel.org/r/20150707070306.GB9784@xxxxxxxxx Luis R.
