patch "iio: addac: ad74413: don't set DIN_SINK for functions other than" added to char-misc-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: addac: ad74413: don't set DIN_SINK for functions other than to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. From a4cba07e64e6ec22d9504a1a45d29afa863dc19c Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes <linux(a)rasmusvillemoes.dk> Date: Wed, 3 May 2023 12:50:41 +0200 Subject: iio: addac: ad74413: don't set DIN_SINK for functions other than digital input Apparently, despite the name Digital Input Configuration Register, the settings in the DIN_CONFIGx registers also affect other channel functions. In particular, setting a non-zero value in the DIN_SINK field breaks the resistance measurement function. Now, one can of course argue that specifying a drive-strength-microamp property along with a adi,ch-func which is not one of the digital input functions is a bug in the device tree. However, we have a rather complicated setup with instances of ad74412r on external hardware modules, and have set a default drive-strength-microamp in our DT fragments describing those, merely modifying the adi,ch-func settings to reflect however the modules have been wired up. And restricting this setting to just being done for digital input doesn't make the driver any more complex.

[PATCH] s390/ism: Fix trying to free already-freed IRQ by repeated ism_dev_exit()

by Julian Ruess

This patch prevents the system from crashing when unloading the ISM module. How to reproduce: Attach an ISM device and execute 'rmmod ism'. Error-Log: - Trying to free already-free IRQ 0 - WARNING: CPU: 1 PID: 966 at kernel/irq/manage.c:1890 free_irq+0x140/0x540 After calling ism_dev_exit() for each ISM device in the exit routine, pci_unregister_driver() will execute ism_remove() for each ISM device. Because ism_remove() also calls ism_dev_exit(), free_irq(pci_irq_vector(pdev, 0), ism) is called twice for each ISM device. This results in a crash with the error 'Trying to free already-free IRQ'. In the exit routine, it is enough to call pci_unregister_driver() because it ensures that ism_dev_exit() is called once per ISM device.
