static void nb7vpq904m_remove(struct i2c_client *client)
In case of error in the nb7vpq904m_probe() probe function, some resources need to be freed, as already done in the remove function. Add the missing error handling path and adjust code accordingly. Fixes: 88d8f3ac9c67 ("usb: typec: add support for the nb7vpq904m Type-C Linear Redriver") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- This changes the order with some devm_ allocated resources. I hope this is fine. At least it is consistent with the remove function. --- drivers/usb/typec/mux/nb7vpq904m.c | 25 ++++++++++++++++++------- 1 file changed, 18 insertions(+), 7 deletions(-)
