I'm referring to multiple other files within qla4xxx source which uses dma_pool_alloc. The current patch takes care only of ql4_mbx.c and qla4xxx_get_chap function. There is qla4xxx_set_chap function as well. Also ql4_init.c and ql4_os.c files also use dma_pool_alloc. I was requesting to make all these changes related to qla4xxx module within a single patch.
