[Bluez-devel] [PATCH] change inquiry_cache to hci_inquiry_cache to avoid possible name conflicts

[Stephen Hemminger <shemminger@osdl.org>]

This patch changes the inquiry_XXX function to be either local to hci_core.c
or change name from inquiry_cache_lookup to hci_inquiry_cache_lookup to try and
reduce the potential for namespace conflicts.  There could be USB or SCSI or other
code that uses an inquiry_cache.
