[PATCH net v3 5/5] r8152: Add RTL8152_INACCESSIBLE to r8153_aldps_en()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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().
