ARM: multiplatform: Sort the max gpio numbers. (2a6ad871) · Commits · 戴 / test

When building a multiplatform kernel, we could end up with a smaller number of GPIOs than the one required by the platform the kernel was running on. Sort the max GPIO number by descending order so that we always take the highest number required. Signed-off-by:
