Since both an __init function and an __exit function can call i915_globals_exit(), any function that i915_globals_exit() calls should not be marked as __init or __exit. I.e., it needs to be available for either of them. WARNING: modpost: vmlinux.o(.text+0x8b796a): Section mismatch in reference from the function i915_globals_exit() to the function .exit.text:__i915_globals_flush() The function i915_globals_exit() references a function in an exit section. Often the function __i915_globals_flush() has valid usage outside the exit section and the fix is to remove the __exit annotation of __i915_globals_flush. ERROR: modpost: Section mismatches detected. Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
