ANDROID_VENDOR_HOOKS has implicit dependencies on the subsystems which
it hooks into whenever it directly uses an "internal" header for that
system. For instance, drivers/scsi/ufs/ufshcd.h doesn't compile unless
CONFIG_SCSI_UFSHCD is enabled:
In file included from drivers/android/vendor_hooks.c:41:
In file included from include/trace/hooks/ufshcd.h:21:
include/../drivers/scsi/ufs/ufshcd.h:675:38: error: field has incomplete type 'struct devfreq_simple_ondemand_data'
struct devfreq_simple_ondemand_data ondemand_data;
^
include/../drivers/scsi/ufs/ufshcd.h:675:9: note: forward declaration of 'struct devfreq_simple_ondemand_data'
struct devfreq_simple_ondemand_data ondemand_data;
To avoid these implicit dependencies, guard any "internal" header
includes with the respective CONFIG_ options when applicable. If the
CONFIG_ option is not enabled, then the forward-declared structs are
used. This is acceptable because those hooks would not have been called
anyway since the underlying subsytem wasn't enabled.
Fixes: commit 1590a0e8e1 ("ANDROID: GKI: include more type definitions in vendor hooks")
