Docs: blackfin: Use new switch macro SAMPLE_IRQ_TIMER instead of IRQ_TIMER5
Not all blackfin machines support IRQ_TIMER5, but all machines support
IRQ_TIMER2. So add a switch macro for them. The related error:
Documentation/blackfin/gptimers-example.c: In function 'gptimer_example_init':
Documentation/blackfin/gptimers-example.c:60:20: error: 'IRQ_TIMER5' undeclared (first use in this function)
ret = request_irq(IRQ_TIMER5, gptimer_example_irq, IRQF_SHARED, DRIVER_NAME, &data);
^
Documentation/blackfin/gptimers-example.c:60:20: note: each undeclared identifier is reported only once for each function it appears in
Documentation/blackfin/gptimers-example.c: In function 'gptimer_example_exit':
Documentation/blackfin/gptimers-example.c:78:11: error: 'IRQ_TIMER5' undeclared (first use in this function)
free_irq(IRQ_TIMER5, &data);
^
Also notice about 80 columns limitation.
