Subject[PATCH 3.18 14/19] rtlwifi: rtl8192ce: Fix missing interrupt ready flag
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit 87141db0848aa20c43d453f5545efc8f390d4372 upstream.

Proper operation with the rewritten PCI mini driver requires that a flag be set
when interrupts are enabled. This flag was missed. This patch is one of three needed to
fix the kernel regression reported at https://bugzilla.kernel.org/show_bug.cgi?id=88951.
