Date: Tue, 28 Mar 2017 11:37:42 +0200 From: Tobias Regnery <tobias.regnery@...il.com> To: robh+dt@...nel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Cc: horms@...ge.net.au, arnd@...db.de, Tobias Regnery <tobias.regnery@...il.com> Subject: [PATCH v2] of: add stubs for of_n_{addr, size}_cells With CONFIG_OF=n and CONFIG_COMPILE_TEST=y the rcar pci-e driver fails to build on arm: drivers/pci/host/pcie-rcar.c: In function 'pci_dma_range_parser_init': drivers/pci/host/pcie-rcar.c:1035:16: error: implicit declaration of function 'of_n_addr_cells' [-Werror=implicit-function-declaration] parser->pna = of_n_addr_cells(node); ^~~~~~~~~~~~~~~ Fix this by adding an inline stub for of_n_addr_cells While at it also provide a stub for of_n_size_cells for consistency reasons.
