| Subject: sh: fix multiple function definition build errors |
| |
| Many of the sh CPU-types have their own plat_irq_setup() and |
| arch_init_clk_ops() functions, so these same (empty) functions in |
| arch/sh/boards/of-generic.c are not needed and cause build errors. If |
| there is some case where these empty functions are needed, they can be |
| retained by marking them as "__weak" while at the same time making builds |
| that do not need them succeed. |
| |
| Fixes these build errors: |
| |
| arch/sh/boards/of-generic.o: In function `plat_irq_setup': |
| (.init.text+0x134): multiple definition of `plat_irq_setup' |
| arch/sh/kernel/cpu/sh2/setup-sh7619.o:(.init.text+0x30): first defined here |
| arch/sh/boards/of-generic.o: In function `arch_init_clk_ops': |
| (.init.text+0x118): multiple definition of `arch_init_clk_ops' |
| arch/sh/kernel/cpu/sh2/clock-sh7619.o:(.init.text+0x0): first defined here |
