Subject: Re: [PATCH] drivers/perf: Add NULL check in tx2_uncore_pmu_register

> When devm_kasprintf() fails, it returns a NULL pointer. However, this return value is not properly checked in the function tx2_uncore_pmu_register.
>
> A NULL check should be added after the devm_kasprintf() to prevent potential NULL pointer dereference error.
