Subject: gpio: max77620: Do not allocate IRQs upfront
Git-commit: 704355db127e4bcc96c40fa3eeff5450f1a14d13
Patch-mainline: v5.5-rc1
References: jsc#SLE-9391,jsc#SLE-9388,jsc#SLE-10608
regmap_add_irq_chip() will try to allocate all of the IRQ descriptors
upfront if passed a non-zero irq_base parameter. However, the intention
is to allocate IRQ descriptors on an as-needed basis if possible. Pass 0
instead of -1 to fix that use-case.
