kernel/linux.git/drivers/clocksource/timer-ralink.c, branch v6.19.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.19.112025-11-26T10:24:34+00:00clocksource/drivers/ralink: Fix resource leaks in init error path2025-11-26T10:24:34+00:00Haotian Zhangvulab@iscas.ac.cn2025-10-30T09:07:10+00:00urn:sha1:2ba8e2aae1324704565a7d4d66f199d056c9e3c6
The ralink_systick_init() function does not release all acquired resources
on its error paths. If irq_of_parse_and_map() or a subsequent call fails,
the previously created I/O memory mapping and IRQ mapping are leaked.
Add goto-based error handling labels to ensure that all allocated
resources are correctly freed.

clocksource/drivers/ralink: Add Ralink System Tick Counter driver2024-11-13T12:49:33+00:00Sergio Paracuellossergio.paracuellos@gmail.com2024-10-28T20:36:43+00:00urn:sha1:cd5375610baadd3a0842a9e83ca502684f938be8
System Tick Counter is present on Ralink SoCs RT3352 and MT7620. This
driver has been in 'arch/mips/ralink' directory since the beggining of
Ralink architecture support. However, it can be moved into a more proper
place in 'drivers/clocksource'. Hence add it here adding also support for
compile test targets and reducing LOC in architecture code folder.
