[PATCH 0/4] scsi: mpi3mr: Replace 1-element arrays with flexible arrays

[Kees Cook]

Hi,

Replace all the uses of deprecated 1-element "fake" flexible arrays
with modern C99 flexible arrays.

Thanks!

-Kees

[PATCH 1/4] scsi: mpi3mr: struct mpi3_event_data_sas_topology_change_list: Replace 1-element array with flexible array

[Kees Cook]

Replace the deprecated[1] use of a 1-element array in
struct mpi3_event_data_sas_topology_change_list with a modern
flexible array.

Additionally add __counted_by annotation since phy_entry is only ever
accessed in loops controlled by num_entries. For example:

        for (i = 0; i < event_data->num_entries; i++) {
		...
                handle = le16_to_cpu(event_data->phy_entry[i].attached_dev_handle);

No binary differences are present after this conversion.

[PATCH 2/4] scsi: mpi3mr: struct mpi3_event_data_pcie_topology_change_list: Replace 1-element array with flexible array

[Kees Cook]

Replace the deprecated[1] use of a 1-element array in
struct mpi3_event_data_pcie_topology_change_list with a modern
flexible array.

Additionally add __counted_by annotation since port_entry is only ever
accessed in loops controlled by num_entries. For example:

        for (i = 0; i < event_data->num_entries; i++) {
                handle =
                    le16_to_cpu(event_data->port_entry[i].attached_dev_handle);
