From 8674cabe052b9ce23f72abb83058fc1d545e257a Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 12 Apr 2021 11:38:12 +0200 Subject: [PATCH] USB: serial: f81232: drop time-based drain delay The f81232 driver now waits for the transmit FIFO to drain during close so there is no need to keep the time-based drain delay, which would add up to two seconds on every close for low line speeds.
