There is no need to test the result of any debugfs call anymore. The debugfs core warns the user if something fails, and the return value of a debugfs call can always be fed back into another debugfs call with no problems.
Also, debugfs is for debugging, so if there are problems with debugfs (i.e. the system is out of memory) the rest of the kernel should not change behavior, so testing for debugfs calls is pointless and not the goal of debugfs at all. This series cleans up a lot of networking drivers and some wimax code that was calling debugfs and trying to do something with the return value that it didn't need to. Removing this logic makes the code smaller, easier to understand, and use less run-time memory in some cases, all good things. The series is against net-next, and have no dependancies between any of them if they want to go through any random tree/order. Or, if wanted, I can take them through my driver-core tree where other debugfs cleanups are being slowly fed during major merge windows. thanks, greg k-h Greg Kroah-Hartman (17): wimax: no need to check return value of debugfs_create functions bonding: no need to print a message if debugfs_create_dir() fails mlx5: no need to check return value of debugfs_create functions xgbe: no need to check return value of debugfs_create functions bnxt: no need to check return value of debugfs_create functions cxgb4: no need to check return value of debugfs_create functions hns3: no need to check return value of debugfs_create functions nfp: no need to check return value of debugfs_create functions stmmac: no need to check return value of debugfs_create functions dpaa2: no need to check return value of debugfs_create functions qca: no need to check return value of debugfs_create functions skge: no need to check return value of debugfs_create functions mvpp2: no need to check return value of debugfs_create functions fm10k: no need to check return value of debugfs_create functions i40e: no need to check return value of debugfs_create functions ixgbe: no need to check return value of debugfs_create functions ieee802154: no need to check return value of debugfs_create functions drivers/net/bonding/bond_debugfs.c | 5 - drivers/net/ethernet/amd/xgbe/xgbe-debugfs.c | 107 ++++--------- drivers/net/ethernet/broadcom/bnxt/bnxt.h | 1 - .../net/ethernet/broadcom/bnxt/bnxt_debugfs.c | 39 ++--- .../ethernet/chelsio/cxgb4/cxgb4_debugfs.c | 5 +- .../net/ethernet/chelsio/cxgb4/cxgb4_main.c | 3 - .../ethernet/chelsio/cxgb4vf/cxgb4vf_main.c | 21 +-- .../freescale/dpaa2/dpaa2-eth-debugfs.c | 54 +------ .../freescale/dpaa2/dpaa2-eth-debugfs.h | 3 - .../ethernet/hisilicon/hns3/hns3_debugfs.c | 17 +- .../net/ethernet/intel/fm10k/fm10k_debugfs.c | 2 - .../net/ethernet/intel/i40e/i40e_debugfs.c | 21 +-- .../net/ethernet/intel/ixgbe/ixgbe_debugfs.c | 22 +-- .../ethernet/marvell/mvpp2/mvpp2_debugfs.c | 19 +-- drivers/net/ethernet/marvell/skge.c | 39 ++--- drivers/net/ethernet/mellanox/mlx5/core/cmd.c | 51 +----- .../net/ethernet/mellanox/mlx5/core/debugfs.c | 102 ++---------- drivers/net/ethernet/mellanox/mlx5/core/eq.c | 11 +- .../net/ethernet/mellanox/mlx5/core/lib/eq.h | 2 +- .../net/ethernet/mellanox/mlx5/core/main.c | 7 +- .../ethernet/mellanox/mlx5/core/mlx5_core.h | 2 +- .../ethernet/netronome/nfp/nfp_net_debugfs.c | 17 +- drivers/net/ethernet/qualcomm/qca_debug.c | 13 +- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 2 - .../net/ethernet/stmicro/stmmac/stmmac_main.c | 52 +----- drivers/net/ieee802154/adf7242.c | 12 +- drivers/net/ieee802154/at86rf230.c | 20 +-- drivers/net/ieee802154/ca8210.c | 9 +- drivers/net/wimax/i2400m/debugfs.c | 149 +++--------------- drivers/net/wimax/i2400m/driver.c | 7 +- drivers/net/wimax/i2400m/i2400m.h | 7 +- drivers/net/wimax/i2400m/usb.c | 61 ++----- include/linux/mlx5/driver.h | 12 +- include/linux/wimax/debug.h | 20 +-- net/wimax/debugfs.c | 42 +---- net/wimax/stack.c | 11 +- net/wimax/wimax-internal.h | 7 +- 37 files changed, 175 insertions(+), 799 deletions(-) -- 2.22.0
