+Subject: of: net: pass the dst buffer to of_get_mac_address()
+
+of_get_mac_address() returns a "const void*" pointer to a MAC address.
+Lately, support to fetch the MAC address by an NVMEM provider was added.
+But this will only work with platform devices. It will not work with
+PCI devices (e.g. of an integrated root complex) and esp. not with DSA
+ports.
+
+There is an of_* variant of the nvmem binding which works without
+devices. The returned data of a nvmem_cell_read() has to be freed after
+use. On the other hand the return of_get_mac_address() points to some
+static data without a lifetime. The trick for now, was to allocate a
+device resource managed buffer which is then returned. This will only
+work if we have an actual device.
+
+Change it, so that the caller of of_get_mac_address() has to supply a
+buffer where the MAC address is written to. Unfortunately, this will
+touch all drivers which use the of_get_mac_address().
+
+Usually the code looks like:
+
+ const char *addr;
+ addr = of_get_mac_address(np);
+ if (!IS_ERR(addr))
+ ether_addr_copy(ndev->dev_addr, addr);
+
+This can then be simply rewritten as:
+
+ of_get_mac_address(np, ndev->dev_addr);
+
+Sometimes is_valid_ether_addr() is used to test the MAC address.
+of_get_mac_address() already makes sure, it just returns a valid MAC
+address. Thus we can just test its return code. But we have to be
+careful if there are still other sources for the MAC address before the
+of_get_mac_address(). In this case we have to keep the
+is_valid_ether_addr() call.
+
+The following coccinelle patch was used to convert common cases to the
+new style. Afterwards, I've manually gone over the drivers and fixed the
+return code variable: either used a new one or if one was already
+available use that. Mansour Moufid, thanks for that coccinelle patch!
