Hi Felipe, After merging the usb-gadget tree, today's linux-next build (x86_64 allmodconfig) produced these warnings: drivers/staging/iio/frequency/ad9832.c: In function 'ad9832_probe': drivers/staging/iio/frequency/ad9832.c:214:11: warning: 'st' may be used uninitialized in this function [-Wmaybe-uninitialized] st->avdd = devm_regulator_get(&spi->dev, "avdd"); ^ This was probably because -Wmaybe-uninitialized has been reenabled in Linus' tree In file included from drivers/staging/vc04_services/interface/vchiq_arm/vchiq_core.c:35:0:
