Is it wise to use the uses_dma flag as a bit mask to show DMA properties and avoid adding additional u8? Something like: DMA_NONE (0) DMA_ENABLE_BULK (1<0) DMA_ENABLE_CONTROL (1<1) So that if (uses_dma) still continues to work And anyone having a need or CONTROL DMA can check explicitly... > u8 otg_port; /* 0, or number of OTG/HNP port */ > unsigned is_b_host:1; /* true during some HNP roleswitches */ > unsigned b_hnp_enable:1; /* OTG: did A-Host enable HNP? */ <snip> -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
