Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods<br />
<br />
drvdata::gpiods is supposed to hold an array of &#39;gpio_desc&#39; pointers. But<br />
the memory is allocated for only one pointer. This will lead to<br />
out-of-bounds access later in the code if &#39;config::ngpios&#39; is > 1. So<br />
fix the code to allocate enough memory to hold &#39;config::ngpios&#39; of GPIO<br />
descriptors.<br />
<br />
While at it, also move the check for memory allocation failure to be below<br />
the allocation to make it more readable.
