Kuan-Wei Chiu 54c14022fa printk: Fix signed integer overflow when defining LOG_BUF_LEN_MAX ... [ Upstream commit 3d6f83df8f ] Shifting 1 << 31 on a 32-bit int causes signed integer overflow, which leads to undefined behavior. To prevent this, cast 1 to u32 before performing the shift, ensuring well-defined behavior. This change explicitly avoids any potential overflow by ensuring that the shift occurs on an unsigned 32-bit integer.
