Subject: r8152: don't execute runtime suspend if the tx is not empty
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6a0b76c04ec157c88ca943debf78a8ee58469f2d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

r8152: don't execute runtime suspend if the tx is not empty

Runtime suspend shouldn't be executed if the tx queue is not empty,
because the device is not idle.
