[PATCHv1 0/4] Remove unsafe batostr

[Andrei Emeltchenko]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Since the patch "vsprintf: add %pMR for Bluetooth MAC address" in in linux-next and wireless-testing
remove batostr.

http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commitdiff;h=76597ff989a1fbaa9b9a1e54007cd759bf257ab7

Andrei Emeltchenko (4):
  Bluetooth: Use %pMR BT addr print spec instead of batostr
  Bluetooth: trivial: Shorten variable scope
  Bluetooth: Use %pMR instead of baswap in seq_show
  Bluetooth: trivial: Use preferred method for NULL check

[PATCHv1 1/4] Bluetooth: Use %pMR BT addr print spec instead of batostr

[Andrei Emeltchenko]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Clean up old unsafe batostr function and use %pMR print specifier
for printing Bluetooth addresses.

[PATCHv2 0/4] Remove unsafe batostr

[Andrei Emeltchenko]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Since the patch "vsprintf: add %pMR for Bluetooth MAC address" in in bluetooth-next resend the patch series.

Changes:
	* v2: Rebase against recent bluetooth-next.

Andrei Emeltchenko (4):
  Bluetooth: Use %pMR in debug instead of batostr
  Bluetooth: Use %pMR in sprintf/seq_printf  instead of batostr
  Bluetooth: Use %pMR instead of baswap in seq_show
  bluetooth: Remove unneeded batostr function

[PATCHv2 2/4] Bluetooth: Use %pMR in sprintf/seq_printf instead of batostr

[Andrei Emeltchenko]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Instead of old unsafe batostr function use %pMR print specifier
for printing Bluetooth addresses in sprintf and seq_printf
statements.
