| Subject: [PATCH 088/286] soc: renesas: Provide dummy rcar_rst_read_mode_pins() |
| for compile-testing |
| |
| If the R-Car RST driver is not included, compile-testing R-Car clock |
| drivers fails with a link error: |
| |
| undefined reference to `rcar_rst_read_mode_pins' |
| |
| To fix this, provide a dummy version. Use the exact same test logic as |
| in drivers/soc/renesas/Makefile, as there is no Kconfig symbol (yet) to |
| control compilation of the R-Car RST driver. |
| |
| Fixes: 527c02f66d263d2e ("soc: renesas: Add R-Car RST driver") |
