When adding conftest tests for detecting if specific functions are present, it is always better to check if the newly added function is present versus the function that has been removed. The reason being that is the newly added function is modified in the future then the conftest tests can be extended to check for updates to the function. Therefore, instead of checking if the function gpiochip_find() is present, which was removed in Linux v6.7, check if the function gpio_device_find() is present, which replaced gpiochip_find in Linux v6.7.

# NV_KERNEL_SOURCES : The root of the kernel source tree.

# NV_KERNEL_OUTPUT : The kernel's output tree.

# ARCH : The target CPU architecture: x86_64|arm64|powerpc

# Kbuild provides the variables:

|
|
# - Append to the NV_CONFTEST_*_COMPILE_TESTS variables to indicate

|

# - Append to the NV_OBJECTS_DEPEND_ON_CONFTEST variable any object files
