From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- drivers/rtc/nvmem.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 drivers/rtc/nvmem.c (limited to 'drivers/rtc/nvmem.c') diff --git a/drivers/rtc/nvmem.c b/drivers/rtc/nvmem.c new file mode 100644 index 000000000..37df7e805 --- /dev/null +++ b/drivers/rtc/nvmem.c @@ -0,0 +1,31 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * RTC subsystem, nvmem interface + * + * Copyright (C) 2017 Alexandre Belloni + */ + +#include +#include +#include +#include + +int devm_rtc_nvmem_register(struct rtc_device *rtc, + struct nvmem_config *nvmem_config) +{ + struct device *dev = rtc->dev.parent; + struct nvmem_device *nvmem; + + if (!nvmem_config) + return -ENODEV; + + nvmem_config->dev = dev; + nvmem_config->owner = rtc->owner; + nvmem_config->add_legacy_fixed_of_cells = true; + nvmem = devm_nvmem_register(dev, nvmem_config); + if (IS_ERR(nvmem)) + dev_err(dev, "failed to register nvmem device for RTC\n"); + + return PTR_ERR_OR_ZERO(nvmem); +} +EXPORT_SYMBOL_GPL(devm_rtc_nvmem_register); -- cgit v1.3.1
