This driver uses readw() and writew() which are declared in asm/io.h but does not explicitly include that header, causing build failures on architectures where there is not an implicit inclusion such as arm and arm64: ../drivers/i2c/busses/i2c-jz4780.c:181:2: error: implicit declaration of function 'readw' [-Werror=implicit-function-declaration] ../drivers/i2c/busses/i2c-jz4780.c:187:2: error: implicit declaration of function 'writew' [-Werror=implicit-function-declaration] Add an explicit inclusion to fix this.
