Также может иметь смысл повесить в bugzilla.kernel.org, но всё равно обязательно в рассылку, как показывают предыдущие случаи.
(В ответ на комментарий №4) > Также может иметь смысл повесить в bugzilla.kernel.org, но всё равно > обязательно в рассылку, как показывают предыдущие случаи. В bugzilla.kernel.org зафиксировал и ошибку, и патч. см. https://bugzilla.kernel.org/show_bug.cgi?id=74041 Не обессудьте - в рассылку мне писать слабО.
(В ответ на комментарий №5) > см. https://bugzilla.kernel.org/show_bug.cgi?id=74041 О, там Грег глянул: https://bugzilla.kernel.org/show_bug.cgi?id=74041#c1 > Не обессудьте - в рассылку мне писать слабО. И всё-таки если ещё не поправили -- лучше написать; именно про linux-usb@ не скажу, но в linux-kernel@ подписка не требуется, нам отвечали с копией. На всё про всё с чтением документации и приведением патча в требуемый вид может уйти с полчаса; если всё-таки надо, но затруднительно, давайте попробуем вместе.
