In the Linux kernel, the following vulnerability has been resolved:
gpiolib: fix memory leak in gpiod_set_array_value_complex() on error paths
A drive-by review by Sashiko reports that, after a failed call to
gpiochip_set_multiple(), gpiod_set_array_value() returns abruptly,
bypassing the freeing of possibly alloced bitmaps, potentially leaking
memory. It is an unlikely error path, but is possible.
Defer the return code check until after the bitmap_free() block.
