------------------ From: Arnd Bergmann <[email protected]> commit 4a236d01b5e0d7e6f4ee9e6c4056fce10b38e8ad upstream. The newly added Hi6220 Ion code fails to build when the ION_OF helpers are not present: drivers/staging/android/ion/hisilicon/hi6220_ion.o: In function `hi6220_ion_remove': hi6220_ion.c:(.text.hi6220_ion_remove+0x4c): undefined reference to `ion_destroy_platform_data' drivers/staging/android/ion/hisilicon/hi6220_ion.o: In function `hi6220_ion_probe': hi6220_ion.c:(.text.hi6220_ion_probe+0x5c): undefined reference to `ion_parse_dt' hi6220_ion.c:(.text.hi6220_ion_probe+0xf8): undefined reference to `ion_destroy_platform_data' This selects the symbol when needed.
