And looking into definition for no_irq_type (include/linux/irq.h):
/*
* Migration helpers for obsolete names, they will go away:
*/
#define hw_interrupt_type irq_chip
#define no_irq_type no_irq_chip
typedef struct irq_desc irq_desc_t;
We can see that "no_irq_type" is being made obsoleted:
For eg:
http://git.kernel.org/?p=linux/kernel/git/aegl/linux-2.6.git;a=blobdiff;f=arch/mn10300/kernel/irq.c;h=4c3c58ef5cda6fe571cbe39a649e8d4ebbfc3ae0;hp=50fdb5c16e0c34368e4faad479d041b4b4362eb9;hb=91e58b6e95a9c6b9efd928ae352eae5e75ae598c;hpb=df5529297ec4c32d57dd149398e3add6c37bc054

But looking further into existing source:
./ia64/hp/sim/hpsim_irq.c:
if (idesc->chip == &no_irq_type)
./ia64/sn/kernel/irq.c:
if (base_desc[i].chip == &no_irq_type) {
./ia64/kernel/iosapic.c:
if (idesc->chip != &no_irq_type)
./sh/kernel/sh_ksyms_32.c:
extern struct hw_interrupt_type no_irq_type;
EXPORT_SYMBOL(no_irq_type);
Does it make sense that I can change all these to no_irq_chip?
Purely naming change in nature.
Thanks.
