In function 'dra7xx_pcie_init_irq_domain', the pattern used to check and return error is: if (!var) { dev_err(...); return PTR_ERR(var); } So the returned value in case of error is always 0, which means 'success'. Change it to return -ENODEV instead. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- drivers/pci/host/pci-dra7xx.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
