Looks like the only reason the pdev is needed is for retrieving the pdev id, which is also stored in the omap_dm_timer structure? > u32 timer_capability; > u32 timer_errata; > int (*get_context_loss_count)(struct device *); > + struct omap_dm_timer_ops *timer_ops; Any reason why this is not a const? We don't expect this to change right. regards Suman > }; > > #endif /* __PLATFORM_DATA_DMTIMER_OMAP_H__ */ > -- > 1.9.1 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@...ts.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel >
