This fixes a `WARN_ON' and allows the driver to operate GPIOs which are connected to I2C GPIO expanders. -- >8 -- kernel: WARNING: CPU: 3 PID: 2636 at drivers/gpio/gpiolib.c:3880 gpiod_set_value+0x88/0x98 -- >8 -- Fixes: 43201767b44c ("NFC: nxp-nci: Convert to use GPIO descriptor") Cc: stable@vger.kernel.org Signed-off-by: Ian Ray --- Changes since v2: - Correct the fixes tag (found by AI review) - Use uppercase "NFC" in patch prefix --- drivers/nfc/nxp-nci/i2c.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/nfc/nxp-nci/i2c.c b/drivers/nfc/nxp-nci/i2c.c index 6a5ce8ff91f0..b3d34433bd14 100644 --- a/drivers/nfc/nxp-nci/i2c.c +++ b/drivers/nfc/nxp-nci/i2c.c @@ -47,8 +47,8 @@ static int nxp_nci_i2c_set_mode(void *phy_id, { struct nxp_nci_i2c_phy *phy = (struct nxp_nci_i2c_phy *) phy_id; - gpiod_set_value(phy->gpiod_fw, (mode == NXP_NCI_MODE_FW) ? 1 : 0); - gpiod_set_value(phy->gpiod_en, (mode != NXP_NCI_MODE_COLD) ? 1 : 0); + gpiod_set_value_cansleep(phy->gpiod_fw, (mode == NXP_NCI_MODE_FW) ? 1 : 0); + gpiod_set_value_cansleep(phy->gpiod_en, (mode != NXP_NCI_MODE_COLD) ? 1 : 0); usleep_range(10000, 15000); if (mode == NXP_NCI_MODE_COLD) -- 2.49.0
