workqueue: skip the node_nr_active update for non-unbound workqueuesgrafted
apply_wqattrs_commit() updates node_nr_active->max unconditionally. wq->node_nr_active[] is only allocated for unbound workqueues, so guard the call before per-cpu workqueues start using this path. No functional change: only unbound workqueues reach apply_wqattrs_*() today. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org>

+config NFC_TRF7970A
+ tristate "Texas Instruments TRF7970a NFC driver"
+ depends on SPI && NFC_DIGITAL && GPIOLIB
+ help
+ This option enables the NFC driver for Texas Instruments' TRF7970a
+ device. Such device supports 5 different protocols: ISO14443A,
+ ISO14443B, FeLiCa, ISO15693 and ISO18000-3.
+
+ Say Y here to compile support for TRF7970a into the kernel or
+ say M to compile it as a module. The module will be called
+ trf7970a.ko.
+
+config NFC_MEI_PHY
+ tristate "MEI bus NFC device support"
+ depends on INTEL_MEI && NFC_HCI
+ help
+ This adds support to use an mei bus nfc device. Select this if you
+ will use an HCI NFC driver for an NFC chip connected behind an
+ Intel's Management Engine chip.
+
+ If unsure, say N.
+
+config NFC_SIM
+ tristate "NFC hardware simulator driver"
+ depends on NFC_DIGITAL
+ help
+ This driver declares two virtual NFC devices supporting NFC-DEP
+ protocol. An LLCP connection can be established between them and
+ all packets sent from one device is sent back to the other, acting as
+ loopback devices.
+
+ If unsure, say N.
+
+config NFC_PORT100

+ depends on USB
+ depends on NFC_DIGITAL
+ help
+ This adds support for Sony Port-100 chip based USB devices such as the
+ RC-S380 dongle.
+
+ If unsure, say N.
+
+config NFC_VIRTUAL_NCI
+ tristate "NCI device simulator driver"
+ depends on NFC_NCI
+ help
+ NCI virtual device simulates a NCI device to the user.
+ It can be used to validate the NCI module and applications.
+ This driver supports communication between the virtual NCI device and
+ module.
+
+ If unsure, say N.
