This patch replaces all the code snippets that reads the model name from the device tree with the newly added helper function: of_machine_get_model_name Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> --- arch/arm/mach-imx/cpu.c | 5 +---- arch/arm/mach-mxs/mach-mxs.c | 4 +--- arch/mips/cavium-octeon/setup.c | 12 ++---------- arch/mips/generic/proc.c | 15 +++------------ arch/sh/boards/of-generic.c | 8 +------- drivers/soc/fsl/guts.c | 8 ++------ drivers/soc/renesas/renesas-soc.c | 4 +--- 7 files changed, 11 insertions(+), 45 deletions(-) Hi, This patch is just to show the use of PATCH 1/2. It needs to go after 1/2 is merged for sake of simplicity and avoid cross dependencies (targetting v4.11) Regards, Sudeep -- 2.7.4
