If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 4e6d018776e222cca9b6c605e1c6716019abffe1 Author: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Sun Jun 12 23:12:20 2022 +0200 wifi: p54: Fix an error handling path in p54spi_probe() [ Upstream commit 83781f0162d080fec7dcb911afd1bc2f5ad04471 ] If an error occurs after a successful call to p54spi_request_firmware(), it must be undone by a corresponding release_firmware() as already done in the error handling path of p54spi_request_firmware() and in the .remove() function. Add the missing call in the error handling path and remove it from p54spi_request_firmware() now that it is the responsibility of the caller to release the firmware Fixes: cd8d3d321285 ("p54spi: p54spi driver") Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Acked-by: Christian Lamparter <chunkeey@xxxxxxxxx> Signed-off-by: Kalle Valo <kvalo@xxxxxxxxxx> Link: https://lore.kernel.org/r/297d2547ff2ee627731662abceeab9dbdaf23231.1655068321.git.christophe.jaillet@xxxxxxxxxx Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/net/wireless/intersil/p54/p54spi.c b/drivers/net/wireless/intersil/p54/p54spi.c index e41bf042352e..3dcfad5b61ff 100644 --- a/drivers/net/wireless/intersil/p54/p54spi.c +++ b/drivers/net/wireless/intersil/p54/p54spi.c @@ -177,7 +177,7 @@ static int p54spi_request_firmware(struct ieee80211_hw *dev) ret = p54_parse_firmware(dev, priv->firmware); if (ret) { - release_firmware(priv->firmware); + /* the firmware is released by the caller */ return ret; } @@ -672,6 +672,7 @@ static int p54spi_probe(struct spi_device *spi) return 0; err_free_common: + release_firmware(priv->firmware); free_irq(gpio_to_irq(p54spi_gpio_irq), spi); err_free_gpio_irq: gpio_free(p54spi_gpio_irq);
