Vulnerability Title
iio: light: gp2ap002: fix runtime PM leak on read error
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: iio: light: gp2ap002: fix runtime PM leak on read error gp2ap002_read_raw() calls pm_runtime_get_sync() before reading the lux value, but if gp2ap002_get_lux() fails, it returns directly. This skips the pm_runtime_put_autosuspend() call at the "out" label, permanently leaking a runtime PM reference and preventing the device from autosuspending. Replace the direct return with a "goto out" to ensure the reference is properly dropped on the error path.

Vulnerability Description
Linux kernel是美国Linux基金会开源的一款操作系统内核。 Linux kernel 5.8版本存在安全漏洞，该漏洞源于gp2ap002_read_raw函数在读取lux值时，如果gp2ap002_get_lux失败，直接返回而不释放运行时PM引用，导致引用泄漏，阻止设备自动挂起。
