Subject: [PATCH v1] Bluetooth: introduce DEFINE_SHOW_ATTRIBUTE() macro
Date: Wed, 22 Nov 2017 23:15:46 +0200 [thread overview]
Message-ID: <20171122211546.5682-1-andriy.shevchenko@linux.intel.com> (raw)
This macro deduplicates a lot of similar code across the hci_debugfs.c
module. Targeting to be moved to seq_file.h eventually.
