Subject: [PATCH] hwmon: (acpi_power_meter) Replace deprecated strcpy() with strscpy()
Merged: 31 Jan 2026, by Guenter Roeck
strcpy() performs no bounds checking on the destination buffer, which could result in linear overflows beyond the end of the buffer. Although the source strings here are compile-time constants that fit within the destination buffers, using strscpy() is the preferred approach as it provides bounds checking and aligns with the kernel's deprecated API guidelines.
This change converts the remaining strcpy() calls to strscpy(), matching the pattern already used throughout other ACPI drivers in drivers/acpi/*.c.
