Subject: rtlwifi: rtl8192ce: Fix missing interrupt ready flag
From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>
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.
