From 6ec1896b5331563fedf3f01014aba9c9e35d7f29 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Iva=20Kasprzakov=C3=A1?= Date: Wed, 22 Jul 2026 15:08:49 +0200 Subject: [PATCH] Bluetooth: fix BT dependency for submodules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The modules rfcomm (BT_RFCOMM), bnep (BT_BNEP), hidp (BT_HIDP), and bluetooth_6lowpan (BT_6LOWPAN) are dependent on the bluetooth module (BT, tristate) only transitively through the boolean BT_BREDR for the first three and through the boolean BT_LE for the bluetooth_6lowpan. Therefore, the modules can be selected as built-in even if the BT=m. The combination of BT=m and =y for the said modules leads to the kernel build system silently ignoring those modules, without ever compiling them as built-in or as loadable modules. Add BT as a direct dependency to the Kconfig of rfcomm, bnep, hidp, and bluetooth_6lowpan. The modules set to =y when BT=m will default to =m, rather then getting silently ignored by the build system.
