It seems like you are using an out of tree driver? The vme_dma_free() function is never called so adding a kfree() shouldn't change anything. But it would make it match vme_lm_free() and vme_master_free() so it's probably the right thing I suppose. regards, dan carpenter _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
