6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Douglas Anderson <dianders@xxxxxxxxxxxx> [ Upstream commit 79321a793945fdbff2f405f84712d0ab81bed287 ] Delay loops in r8152 should break out if RTL8152_INACCESSIBLE is set so that they don't delay too long if the device becomes inaccessible. Add the break to the loop in r8153_aldps_en().
