From c3c9ef598cd03a05e24a85d1dcbd26db70df01d0 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Tue, 13 Dec 2022 00:15:28 +0100 Subject: [PATCH] generic: fix wrong PTR_ERR use in of net mac address ascii patch nvmem_cell_read return a pointer error when an error occurs. Currently we convert the pointer error to an int while the rest of the function return a void* and expcet an error pointer. Fix this PTR_ERR msuse fixing compilation warning. Fixes the following compilation warning: net/ethernet/eth.c: In function 'nvmem_cell_get_mac_address': net/ethernet/eth.c:547:24: warning: returning 'long int' from a function with return type 'void *' makes pointer from integer without a cast [-Wint-conversion] 547 | return PTR_ERR(mac); | ^~~~~~~~~~~~ net/ethernet/eth.c: In function 'nvmem_cell_get_mac_address_ascii': net/ethernet/eth.c:564:24: warning: returning 'long int' from a function with return type 'void *' makes pointer from integer without a cast [-Wint-conversion] 564 | return PTR_ERR(mac_ascii); | ^~~~~~~~~~~~~~~~~~ Fixes: 7b863af180da ("kernel: move mac-address-ascii patches to generic") Signed-off-by: Christian Marangi --- .../hack-5.10/601-of_net-add-mac-address-ascii-support.patch | 4 ++-- .../hack-5.15/601-of_net-add-mac-address-ascii-support.patch | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/target/linux/generic/hack-5.10/601-of_net-add-mac-address-ascii-support.patch b/target/linux/generic/hack-5.10/601-of_net-add-mac-address-ascii-support.patch index f73e262bba..5dd70f5f71 100644 --- a/target/linux/generic/hack-5.10/601-of_net-add-mac-address-ascii-support.patch +++ b/target/linux/generic/hack-5.10/601-of_net-add-mac-address-ascii-support.patch @@ -22,7 +22,7 @@ Submitted-by: Yousong Zhou + + mac = nvmem_cell_read(cell, &len); + if (IS_ERR(mac)) -+ return PTR_ERR(mac); ++ return mac; + if (len != ETH_ALEN) { + kfree(mac); + return ERR_PTR(-EINVAL); @@ -39,7 +39,7 @@ Submitted-by: Yousong Zhou + + mac_ascii = nvmem_cell_read(cell, &len); + if (IS_ERR(mac_ascii)) -+ return PTR_ERR(mac_ascii); ++ return mac_ascii; + if (len != ETH_ALEN*2+5) { + kfree(mac_ascii); + return ERR_PTR(-EINVAL); diff --git a/target/linux/generic/hack-5.15/601-of_net-add-mac-address-ascii-support.patch b/target/linux/generic/hack-5.15/601-of_net-add-mac-address-ascii-support.patch index 83483751f8..4ab05b4ea6 100644 --- a/target/linux/generic/hack-5.15/601-of_net-add-mac-address-ascii-support.patch +++ b/target/linux/generic/hack-5.15/601-of_net-add-mac-address-ascii-support.patch @@ -22,7 +22,7 @@ Submitted-by: Yousong Zhou + + mac = nvmem_cell_read(cell, &len); + if (IS_ERR(mac)) -+ return PTR_ERR(mac); ++ return mac; + if (len != ETH_ALEN) { + kfree(mac); + return ERR_PTR(-EINVAL); @@ -39,7 +39,7 @@ Submitted-by: Yousong Zhou + + mac_ascii = nvmem_cell_read(cell, &len); + if (IS_ERR(mac_ascii)) -+ return PTR_ERR(mac_ascii); ++ return mac_ascii; + if (len != ETH_ALEN*2+5) { + kfree(mac_ascii); + return ERR_PTR(-EINVAL); -- 2.30.2
