* fsl/fman: Remove comment referring to non-existent functionChris Packham2019-07-251-3/+0
| | | | | | | | | | | | fm_set_max_frm() existed in the Freescale SDK as a callback for an early_param. When this code was ported to the upstream kernel the early_param was converted to a module_param making the reference to the function incorrect. The rest of the comment already does a good job of explaining the parameter so removing the reference to the non-existent function seems like the best thing to do.

* ethernet: fman: fix wrong of_node_put() in probe functionNicolas Saenz Julienne2018-12-051-3/+2
| | | | | | | | | | | | | After getting a reference to the platform device's of_node the probe function ends up calling of_find_matching_node() using the node as an argument. The function takes care of decreasing the refcount on it. We are then incorrectly decreasing the refcount on that node again. This patch removes the unwarranted call to of_node_put().

* remove lots of IS_ERR_VALUE abusesArnd Bergmann2016-05-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most users of IS_ERR_VALUE() in the kernel are wrong, as they pass an 'int' into a function that takes an 'unsigned long' argument. This happens to work because the type is sign-extended on 64-bit architectures before it gets converted into an unsigned type. However, anything that passes an 'unsigned short' or 'unsigned int' argument into IS_ERR_VALUE() is guaranteed to be broken, as are 8-bit integers and types that are wider than 'unsigned long'. Andrzej Hajda has already fixed a lot of the worst abusers that were causing actual bugs, but it would be nice to prevent any users that are not passing 'unsigned long' arguments. This patch changes all users of IS_ERR_VALUE() that I could find on 32-bit ARM randconfig builds and x86 allmodconfig. For the moment, this doesn't change the definition of IS_ERR_VALUE() because there are probably still architecture specific users elsewhere. Almost all the warnings I got are for files that are better off using 'if (err)' or 'if (err < 0)'. The only legitimate user I could find that we get a warning for is the (32-bit only) freescale fman driver, so I did not remove the IS_ERR_VALUE() there but changed the type to 'unsigned long'. For 9pfs, I just worked around one user whose calling conventions are so obscure that I did not dare change the behavior. I was using this definition for testing: #define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \ unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO)) which ends up making all 16-bit or wider types work correctly with the most plausible interpretation of what IS_ERR_VALUE() was supposed to return according to its users, but also causes a compile-time warning for any users that do not pass an 'unsigned long' argument. I suggested this approach earlier this year, but back then we ended up deciding to just fix the users that are obviously broken. After the initial warning that caused me to get involved in the discussion (fs/gfs2/dir.c) showed up again in the mainline kernel, Linus asked me to send the whole thing again.

Add the Data Path Acceleration Architecture Frame Manger Driver. The FMan embeds a series of hardware blocks that implement a group of Ethernet interfaces. This patch adds The FMan configuration, initialization and runtime control routines. The FMan driver supports several hardware versions differentiated by things like: - Different type of MACs - Number of MAC and ports - Available resources - Different hardware errata Signed-off-by: Igal Liberman <igal.liberman@freescale.com> Signed-off-by: David S.
