Cc: Weili Qian Cc: Zhou Wang Cc: Herbert Xu Cc: "David S. Miller" Cc: linux-crypto@vger.kernel.org Signed-off-by: Greg Kroah-Hartman Acked-by: Herbert Xu --- Note, this is a patch that is a prepatory cleanup as part of a larger series of patches that is working on resolving some old driver core design mistakes. It will build and apply cleanly on top of 6.3-rc2 on its own, but I'd prefer if I could take it through my driver-core tree so that the driver core changes can be taken through there for 6.4-rc1. drivers/crypto/hisilicon/qm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/crypto/hisilicon/qm.c b/drivers/crypto/hisilicon/qm.c index e4c84433a88a..fd1a38ee55f8 100644 --- a/drivers/crypto/hisilicon/qm.c +++ b/drivers/crypto/hisilicon/qm.c @@ -3691,7 +3691,7 @@ static ssize_t qm_get_qos_value(struct hisi_qm *qm, const char *buf, unsigned long *val, unsigned int *fun_index) { - struct bus_type *bus_type = qm->pdev->dev.bus; + const struct bus_type *bus_type = qm->pdev->dev.bus; char tbuf_bdf[QM_DBG_READ_LEN] = {0}; char val_buf[QM_DBG_READ_LEN] = {0}; struct pci_dev *pdev;
