GpioInt ACPI event handlers may see there IRQ triggered immediately after requesting the IRQ (esp. level triggered ones). This means that they may run before any other (builtin) drivers have had a chance to register their OpRegion handlers, leading to errors like this: [ 1.133274] ACPI Error: No handler for Region [PMOP] ((____ptrval____)) [UserDefinedRegion] (20180531/evregion-132) [ 1.133286] ACPI Error: Region UserDefinedRegion (ID=141) has no handler (20180531/exfldio-265) [ 1.133297] ACPI Error: Method parse/execution failed \_SB.GPO2._L01, AE_NOT_EXIST (20180531/psparse-516) We already defer the manual initial trigger of edge triggered interrupts by running it from a late_initcall handler, this commit replaces this with deferring the entire acpi_gpiochip_request_interrupts() call till then, fixing the problem of some OpRegions not being registered yet. Note that this removes the need to have a list of edge triggered handlers which need to run, since the entire acpi_gpiochip_request_interrupts() call is now delayed, acpi_gpiochip_request_interrupt() can call these directly now.
