Subject: linux-next: build warnings after merge of the usb-gadget tree
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

I am not sure where the reset of these came from.
