| | | | | | | | | | | | | | | | | | | | | | Looks like to me that the ehea_fw_handles.lock mutex and the ehea_bcmc_regs.lock spinlock are taken much longer than necessary and could as well be pushed inside the functions that need them (ehea_update_firmware_handles() and ehea_update_bcmc_registrations()) rather than at each callsite.

So if we are compiled as IXGBE=y, and DCA is enabled, then we must force INTEL_IOATDMA and therefore DCA to be =y also.
