[XEN PATCH v3] xen/IRQ: address violations of MISRA C: 2012 Rules 8.2 and 8.3

Give a name to unnamed parameters thus addressing violations of MISRA C:2012 Rule 8.2 ("Function types shall be in prototype form with named parameters"). Keep consistency between parameter names and types used in function declarations and the ones used in the corresponding function definitions, thus addressing violations of MISRA C:2012 Rule 8.3 ("All declarations of an object or function shall use the same names and type qualifiers"). No functional changes. Signed-off-by: Federico Serafini <federico.serafini@xxxxxxxxxxx> --- Changes in v3: - uniformed parameter names between arm and x86 for irq_set_affinity(). --- Changes in v2: - use 'pirq' instead of 'irq'; - removed changes involving function pointers. --- xen/arch/arm/include/asm/irq.h | 2 +- xen/arch/arm/irq.c | 6 ++--- xen/include/xen/irq.h | 41 +++++++++++++++++----------------- xen/include/xen/softirq.h | 2 +- 4 files changed, 26 insertions(+), 25 deletions(-) diff --git a/xen/arch/arm/include/asm/irq.h b/xen/arch/arm/include/asm/irq.h index 105b33b37d..c8044b0371 100644 --- a/xen/arch/arm/include/asm/irq.h +++ b/xen/arch/arm/include/asm/irq.h @@ -91,7 +91,7 @@ int platform_get_irq(const struct dt_device_node *device, int index); int platform_get_irq_byname(const struct dt_device_node *np, const char *name); -void irq_set_affinity(struct irq_desc *desc, const cpumask_t *cpu_mask); +void irq_set_affinity(struct irq_desc *desc, const cpumask_t *mask); /* * Use this helper in places that need to know whether the IRQ type is diff --git a/xen/arch/arm/irq.c b/xen/arch/arm/irq.c index 16e56f8945..09648db17a 100644 --- a/xen/arch/arm/irq.c +++ b/xen/arch/arm/irq.c @@ -58,7 +58,7 @@ hw_irq_controller no_irq_type = { static irq_desc_t irq_desc[NR_IRQS]; static DEFINE_PER_CPU(irq_desc_t[NR_LOCAL_IRQS], local_irq_desc); -irq_desc_t *__irq_to_desc(int irq) +struct irq_desc *__irq_to_desc(int irq) { if ( irq < NR_LOCAL_IRQS ) return &this_cpu(local_irq_desc)[irq]; @@ -175,10 +175,10 @@ static inline struct domain *irq_get_domain(struct irq_desc *desc) return irq_get_guest_info(desc)->d; } -void irq_set_affinity(struct irq_desc *desc, const cpumask_t *cpu_mask) +void irq_set_affinity(struct irq_desc *desc, const cpumask_t *mask) { if ( desc != NULL ) - desc->handler->set_affinity(desc, cpu_mask); + desc->handler->set_affinity(desc, mask); } int request_irq(unsigned int irq, unsigned int irqflags, diff --git a/xen/include/xen/irq.h b/xen/include/xen/irq.h index 300625e56d..9747e818f7 100644 --- a/xen/include/xen/irq.h +++ b/xen/include/xen/irq.h @@ -110,22 +110,22 @@ typedef struct irq_desc { #define irq_to_desc(irq) (&irq_desc[irq]) #endif -int init_one_irq_desc(struct irq_desc *); -int arch_init_one_irq_desc(struct irq_desc *); +int init_one_irq_desc(struct irq_desc *desc); +int arch_init_one_irq_desc(struct irq_desc *desc); #define irq_desc_initialized(desc) ((desc)->handler != NULL) extern int setup_irq(unsigned int irq, unsigned int irqflags, - struct irqaction *); + struct irqaction *new); extern void release_irq(unsigned int irq, const void *dev_id); extern int request_irq(unsigned int irq, unsigned int irqflags, void (*handler)(int, void *, struct cpu_user_regs *), - const char * devname, void *dev_id); + const char *devname, void *dev_id); extern hw_irq_controller no_irq_type; void cf_check no_action(int cpl, void *dev_id, struct cpu_user_regs *regs); -unsigned int cf_check irq_startup_none(struct irq_desc *); -void cf_check irq_actor_none(struct irq_desc *); +unsigned int cf_check irq_startup_none(struct irq_desc *desc); +void cf_check irq_actor_none(struct irq_desc *desc); #define irq_shutdown_none irq_actor_none #define irq_disable_none irq_actor_none #define irq_enable_none irq_actor_none @@ -146,7 +146,7 @@ struct pirq { #define pirq_info(d, p) ((struct pirq *)radix_tree_lookup(&(d)->pirq_tree, p)) /* Use this instead of pirq_info() if the structure may need allocating. */ -extern struct pirq *pirq_get_info(struct domain *, int pirq); +extern struct pirq *pirq_get_info(struct domain *d, int pirq); #define pirq_field(d, p, f, def) ({ \ const struct pirq *__pi = pirq_info(d, p); \ @@ -155,30 +155,31 @@ extern struct pirq *pirq_get_info(struct domain *, int pirq); #define pirq_to_evtchn(d, pirq) pirq_field(d, pirq, evtchn, 0) #define pirq_masked(d, pirq) pirq_field(d, pirq, masked, 0) -void pirq_cleanup_check(struct pirq *, struct domain *); +void pirq_cleanup_check(struct pirq *pirq, struct domain *d); #define pirq_cleanup_check(pirq, d) \ ((pirq)->evtchn ?
