From 05cf355367dde36b77c384ec49b94901134304a0 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Sun, 10 Dec 2023 12:17:18 +0000 Subject: [PATCH] conftest: Add test to find if struct gpio_chip has of_node Determine if struct gpio_chip has the of_node member or not. The of_node from struct gpio_chip is removed from commit 70d0fc4288dab ("gpiolib: Get rid of not used of_node member") in Linux 6.2 Bug 4346767 Change-Id: I5ebc86beb7ce527f2e38693dd59907cdd3a8fcf9 Signed-off-by: Laxman Dewangan Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3031548 Tested-by: mobile promotions Reviewed-by: mobile promotions --- scripts/conftest/Makefile | 1 + scripts/conftest/conftest.sh | 18 ++++++++++++++++++ 2 files changed, 19 insertions(+) diff --git a/scripts/conftest/Makefile b/scripts/conftest/Makefile index 07f485fc..ca4847e3 100644 --- a/scripts/conftest/Makefile +++ b/scripts/conftest/Makefile @@ -129,6 +129,7 @@ NV_CONFTEST_FUNCTION_COMPILE_TESTS += netif_set_tso_max_size NV_CONFTEST_FUNCTION_COMPILE_TESTS += netif_napi_add_weight NV_CONFTEST_FUNCTION_COMPILE_TESTS += of_get_named_gpio_flags NV_CONFTEST_FUNCTION_COMPILE_TESTS += of_gpio_named_count +NV_CONFTEST_FUNCTION_COMPILE_TESTS += gpio_chip_struct_has_of_node_present NV_CONFTEST_FUNCTION_COMPILE_TESTS += pde_data NV_CONFTEST_FUNCTION_COMPILE_TESTS += pwm_ops_struct_has_owner NV_CONFTEST_FUNCTION_COMPILE_TESTS += pci_epc_event_ops_struct_has_core_deinit diff --git a/scripts/conftest/conftest.sh b/scripts/conftest/conftest.sh index 6a067f8c..865217eb 100755 --- a/scripts/conftest/conftest.sh +++ b/scripts/conftest/conftest.sh @@ -5496,6 +5496,24 @@ compile_test() { compile_check_conftest "$CODE" "NV_OF_GPIO_NAMED_COUNT_PRESENT" "" "functions" ;; + gpio_chip_struct_has_of_node_present) + # + # Determine if struct gpio_chip has the of_node member or not. + # + # The of_node from struct gpio_chip is removed from commit 70d0fc4288dab + # ("gpiolib: Get rid of not used of_node member") in Linux 6.2 + # + CODE=" + #include + int conftest_gpio_chip_struct_has_of_node_present(void) + { + return offsetof(struct gpio_chip, of_node); + } + " + + compile_check_conftest "$CODE" "NV_GPIO_CHIP_STRUCT_HAS_OF_NODE_PRESENT" "" "types" + ;; + devm_gpio_request_one) # # Determine if devm_gpio_request_one() function is present
