treewide: Replace zero-length array with flexible-array

2020-05-22T21:19:31+00:00

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

enetc: Make MDIO accessors more generic and export to include/linux/fsl

2020-01-06T07:22:32+00:00

Within the LS1028A SoC, the register map for the ENETC MDIO controller is instantiated a few times: for the central (external) MDIO controller, for the internal bus of each standalone ENETC port, and for the internal bus of the Felix switch. Refactoring is needed to support multiple MDIO buses from multiple drivers. The enetc_hw structure is made an opaque type and a smaller enetc_mdio_priv is created. 'mdio_base' - MDIO registers base address - is being parameterized, to be able to work with different MDIO register bases. The ENETC MDIO bus operations are exported from the fsl-enetc-mdio kernel object, the same that registers the central MDIO controller (the dedicated PF). The ENETC main driver has been changed to select it, and use its exported helpers to further register its private MDIO bus. The DSA Felix driver will do the same.

bus: fsl-mc: add the fsl_mc_get_endpoint function

2019-10-31T21:19:45+00:00

Using the newly added fsl_mc_get_endpoint function a fsl-mc driver can find its associated endpoint (another object at the other link of a MC firmware link). The API will be used in the following patch in order to discover the connected DPMAC object of a DPNI. Also, the fsl_mc_device_lookup function is made available to the entire fsl-mc bus driver and not just for the dprc driver. Signed-off-by: Ioana Ciornei Signed-off-by: David S. Miller
