Author: Luis R. Rodriguez <mcgrof@suse.com> Rename dma_*_writecombine() to dma_*_wc(), so that the naming is coherent across the various write-combining APIs. Keep the old names for compatibility for a while, these can be removed at a later time. A guard is left to enable backporting of the rename, and later remove of the old mapping defines …

The semantic patch used for this is as follows: // @@ expression e; local idexpression n; @@ for_each_compatible_node(n, …) { … when != of_node_put(n) when != e = n …

fsl/fman: Delete one function call “put_device” in dtsec_config()
Author: Markus Elfring <elfring@users.sourceforge.net> The Coccinelle semantic patch script “deref_null.cocci” pointed a problem out in the implementation of the function “dtsec_config”. A null pointer was assigned to the data structure member “tbiphy” of the variable “dtsec” if a matching device was not found. A call of the function “put_device” was unnecessary then because a previous …
