5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jinjie Ruan <ruanjinjie@xxxxxxxxxx> [ Upstream commit 394679f322649d06fea3c646ba65f5a0887f52c3 ] disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.
