From 4fb220da0dd03d3699776220d86ac84b38941c0c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 7 Oct 2020 17:38:17 +0300 Subject: [PATCH] gpiolib: Update indentation in driver.rst for code excerpts When TABs are being used to indent the code excerpts inside the bullet lists some of the tools [vim in particular] fail to recognize it and continue interpreting the special characters inside the quoted excerpt. Update indentation in driver.rst for code excerpts to avoid their special interpretation.
