IB/mthca: Stop returning separate error and status from FW commands
Instead of having firmware command functions return an error and also a status, leading to code like: err = mthca_FW_COMMAND(..., &status); if (err) goto out; if (status) { err = -E...; goto out; } all over the place, just handle the FW status inside the FW command handling code (the way mlx4 does it), so we can simply write: err = mthca_FW_COMMAND(...); if (err) goto out; In addition to simplifying the source code, this also saves a healthy chunk of text: add/remove: 0/0 grow/shrink: 10/88 up/down: 510/-3357 (-2847) function old new delta static.trans_table 324 584 +260 mthca_cmd_poll 352 477 +125 mthca_cmd_wait 511 567 +56 mthca_table_put 213 240 +27 mthca_cleanup_db_tab 372 387 +15 __mthca_remove_one 314 323 +9 mthca_cleanup_user_db_tab 275 283 +8 __mthca_init_one 1738 1746 +8 mthca_cleanup 20 21 +1 mthca_MAD_IFC 1081 1082 +1 mthca_MGID_HASH 43 40 -3 mthca_MAP_ICM_AUX 23 20 -3 mthca_MAP_ICM 19 16 -3 mthca_MAP_FA 23 20 -3 mthca_READ_MGM 43 38 -5 mthca_QUERY_SRQ 43 38 -5 mthca_QUERY_QP 59 54 -5 mthca_HW2SW_SRQ 43 38 -5 mthca_HW2SW_MPT 60 55 -5 mthca_HW2SW_EQ 43 38 -5 mthca_HW2SW_CQ 43 38 -5 mthca_free_icm_table 120 114 -6 mthca_query_srq 214 206 -8 mthca_free_qp 662 654 -8 mthca_cmd 38 28 -10 mthca_alloc_db 1321 1311 -10 mthca_setup_hca 1067 1055 -12 mthca_WRITE_MTT 35 22 -13 mthca_WRITE_MGM 40 27 -13 mthca_UNMAP_ICM_AUX 36 23 -13 mthca_UNMAP_FA 36 23 -13 mthca_SYS_DIS 36 23 -13 mthca_SYNC_TPT 36 23 -13 mthca_SW2HW_SRQ 35 22 -13 mthca_SW2HW_MPT 35 22 -13 mthca_SW2HW_EQ 35 22 -13 mthca_SW2HW_CQ 35 22 -13 mthca_RUN_FW 36 23 -13 mthca_DISABLE_LAM 36 23 -13 mthca_CLOSE_IB 36 23 -13 mthca_CLOSE_HCA 38 25 -13 mthca_ARM_SRQ 39 26 -13 mthca_free_icms 178 164 -14 mthca_QUERY_DDR 389 375 -14 mthca_resize_cq 1063 1048 -15 mthca_unmap_eq_icm 123 107 -16 mthca_map_eq_icm 396 380 -16 mthca_cmd_box 90 74 -16 mthca_SET_IB 433 417 -16 mthca_RESIZE_CQ 369 353 -16 mthca_MAP_ICM_page 240 224 -16 mthca_MAP_EQ 183 167 -16 mthca_INIT_IB 473 457 -16 mthca_INIT_HCA 745 729 -16 mthca_map_user_db 816 798 -18 mthca_SYS_EN 157 139 -18 mthca_cleanup_qp_table 78 59 -19 mthca_cleanup_eq_table 168 149 -19 mthca_UNMAP_ICM 143 121 -22 mthca_modify_srq 172 149 -23 mthca_unmap_fmr 198 174 -24 mthca_query_qp 814 790 -24 mthca_query_pkey 343 319 -24 mthca_SET_ICM_SIZE 34 10 -24 mthca_QUERY_DEV_LIM 1870 1846 -24 mthca_map_cmd 1130 1105 -25 mthca_ENABLE_LAM 401 375 -26 mthca_modify_port 247 220 -27 mthca_query_device 884 850 -34 mthca_NOP 75 41 -34 mthca_table_get 287 249 -38 mthca_init_qp_table 333 293 -40 mthca_MODIFY_QP 348 308 -40 mthca_close_hca 131 89 -42 mthca_free_eq 435 390 -45 mthca_query_port 755 705 -50 mthca_free_cq 581 528 -53 mthca_alloc_icm_table 578 524 -54 mthca_multicast_attach 1041 986 -55 mthca_init_hca 326 271 -55 mthca_query_gid 487 431 -56 mthca_free_srq 524 468 -56 mthca_free_mr 168 111 -57 mthca_create_eq 1560 1501 -59 mthca_multicast_detach 790 728 -62 mthca_write_mtt 918 854 -64 mthca_register_device 1406 1342 -64 mthca_fmr_alloc 947 883 -64 mthca_mr_alloc 652 582 -70 mthca_process_mad 1242 1164 -78 mthca_dev_lim 910 830 -80 find_mgm 482 400 -82 mthca_modify_qp 3852 3753 -99 mthca_init_cq 1281 1181 -100 mthca_alloc_srq 1719 1610 -109 mthca_init_eq_table 1807 1679 -128 mthca_init_tavor 761 491 -270 mthca_init_arbel 2617 2098 -519 Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.de>
