In commit 99cd149efe82 ("sgiseeq: replace use of dma_cache_wback_inv"), a call to 'get_zeroed_page()' has been turned into a call to 'dma_alloc_coherent()'. Only the remove function has been updated to turn the corresponding 'free_page()' into 'dma_free_attrs()'. The error hndling path of the probe function has not been updated.
Fix it now.
Rename the corresponding label to something more in line.
Fixes: 99cd149efe82 ("sgiseeq: replace use of dma_cache_wback_inv") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- If 'dma_alloc_coherent()' fails, maybe the message in printk could be improved. The comment above may also not be relevant. --- drivers/net/ethernet/seeq/sgiseeq.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-)
