From: Karun Eagalapati Date: Thu, 3 Aug 2017 14:29:03 +0000 (+0530) Subject: rsi: buffer available interrupt handling X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=67c52a4dafceca8ed63b2d8dc73079059e064399;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git rsi: buffer available interrupt handling BUFFER_AVAILABLE interrupt is sent by firmware to indicate change in buffer status. We should check buffer status while handling this interrupt. Currently buffer status is checked only while dequeueing packets. This patch fixes a data traffic stuck problem observed occasionally.
