The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> In the first case, the only cleanup needed is the unlock, so jump to that directly. Likewise, in the first two failure cases of ptlrpc_lprocfs_nrs_seq_write, no cleanup is needed, so just drop the goto and return directly. Signed-off-by:

Kfree can cope with a null argument, so drop null tests. The semantic patch that identifies this issue is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> The first part of the patch introduces new labels to avoid unnecessary calls to kfree. In addition, lprof->lp_md is always null in the cleanup code at the end of the function, so that kfree is just dropped. Signed-off-by:

Kfree can cope with a null argument, so drop null tests. The semantic patch that finds this issue is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> In the first case, llss can never be null at the point of the kfree anyway. In the second set of changes, the gotos are either eliminated, when no freeing is needed (hss failure case), or rewritten so that there is no call to free on data that has not yet been allocated (free_hss goto case). There is no goto at which attr is not null, so the out label is simply dropped. Signed-off-by:

The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> This patch additionally simplifies one case where the free, and thus the jump to the end of the function, is not needed.

The `COMEDI_SRF_...` macros define flag combinations in the `runflags` member of `struct comedi_subdevice`. They are only used directly in "comedi_fops.c", so move them to there. Signed-off-by:

The `COMEDI_SRF_FREE_SPRIV` flag in the `runflags` member of `struct comedi_subdevice` indicates that the memory pointed to by the `private` member can be automatically freed by the comedi core on subdevice clean-up (when the low-level comedi device is being "detached"). the flag doesn't really belong in `runflags`, but it was somewhere convenient to keep it without having to add a new member to the structure. Rather than access the `COMEDI_SRF_FREE_SPRIV` flag directly, use some new wrapper functions: * comedi_can_auto_free_spriv(s) - checks whether the subdevice's `s->private` points to memory that can be freed automatically. * comedi_set_spriv_auto_free(s) - marks the subdevice as having a `s->private` that points to memory that can be freed automatically. Export `comedi_set_spriv_auto_free()` for use by the low-level comedi driver modules, in particular the "amplc_dio200_common" module. Signed-off-by:

serial2002_setup_subdevices() initializes each subdevice based on the config read from the attached serial device. Part of this initialization is to setup the subdevice range_table_list for the non digital subdevices. The range_table_list is allocated only when a 'range' is passed to the functions. Each channel of the subdevice then has it's 'range' initialized and that range is added to the range_table_list. The logic of this function works but causes Coverity complain about an Explicit null dereference of the allocated 'range_table_list'. Add a check for the 'range_table_list' to quiet the Coverity issue. Reported-by: coverity (CID 1011632) Signed-off-by:

ni_write_caldac() checks the boardinfo 'caldac' array to determine what caldac is used for a given 'addr'. It then calculates the 'bitstring' and number of 'bits' used to write a value to that caldac address. After checking the caldac array, if the number of bits is 0 there is no caldac associated with the address. If this happens we shouldn't try writing to the non-existing caldac.
