From 3c0e51e4e59f45d6f6268223fa4b91de0053b36a Mon Sep 17 00:00:00 2001 From: Lucien Cartier-Tilet Date: Fri, 14 Jan 2022 09:17:25 +0100 Subject: [PATCH] (battery-status-function) Fix errors in Termux * lisp/battery.el (battery-status-function): In Termux, neither /sys/ or /proc/ are readable on phones that are not rooted. This patch makes Emacs verify if they are readable before it attemps reading them (bug#53026).
