Hi -
This patch fixes a NULL-dereference introduced by commit 457520e
("arm: pmu: support pmu/perf on OMAP4").
Some platforms (e.g. vexpress) neither need nor have an instance of
arm_pmu_platdata (plat). Perf support on these platforms was broken by
the original commit.
This patch adds a check for plat before dereferencing any fields.
Looks like a good idea...
- } else if (plat->enable_irq)
+ } else if (plat&& plat->enable_irq) {
plat->enable_irq(irq);
+ }
...you can lose the { } though
