From c728601ea3531dc1f0dcd74c1db1e85e59f2be68 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 24 Apr 2014 23:37:56 -0700 Subject: [PATCH] Input: ads7877 - remove bitrotted comment While searching for users of spi_async() I found a reference in the ad7877 driver to using it to initiate data transfer from the interrupt handler. However there is no code for this, instead the interrupt handler is a threaded handler and uses spi_sync() instead. Remove the bitrotted comment, though in actual fact the use case mentioned is a great use for spi_async() since it would cut down on latency handling the interrupt by saving us a context switch before we start SPI. This was previously implemented, it was removed in commit b534422b2d11 (Input: ad7877 - switch to using threaded IRQ) for code complexity reasons. It may be better to revert that commit instead.
