From 81e41be92ad43b268910dcae78c5a72f79f3d467 Mon Sep 17 00:00:00 2001 From: Tobias Schramm Date: Fri, 14 Aug 2020 20:50:11 +0200 Subject: [PATCH] mmc: mmc_spi: fix timeout calculation Previously the cycle timeout was converted to a microsecond value but then incorrectly treated as a nanosecond timeout. This patch changes the code to convert both the nanosecond timeout and the cycle timeout to a microsecond value and use that directly.
