From: Duncan Sands Date: Fri, 13 Jan 2006 10:12:58 +0000 (+0100) Subject: [PATCH] USBATM: -EILSEQ workaround X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a3673d3cd1cdeec6b503ffa418ca2d5aeff82fd7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [PATCH] USBATM: -EILSEQ workaround Don't throttle on -EILSEQ urb status if requested by a minidriver. It seems the ueagle modems are buggy, giving -EILSEQ when they have no data to send. The ueagle change will be sent separately by the ueagle guys. Patch by Matthieu Castet.
