Hi Loic, > Some GPIO controller drivers request sleepable context and so can't > be accessed from IRQ context. Using gpiod_set/get_value accessors > with such controller leads to a kernel warning since they are > reserved for atomic context (according to the documentation). > > Use the postfixed _cansleep version instead, indicating that context > is safe for sleeping if necessary. Note that this is the case here > since we never toggle the gpio neither from IRQ nor from a spinlocked > section. > > Signed-off-by: Loic Poulain <loic.poulain@xxxxxxxxxx> > --- > drivers/bluetooth/hci_bcm.c | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) patch has been applied to bluetooth-next tree.
