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