Subject: genirq: Fix spurious irq seqfile conversion
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=34769945f7cd9ab470413ffe64426e3ad069f49e;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

genirq: Fix spurious irq seqfile conversion

single_open data argument must be PDE(inode)->data instead of NULL
otherwise seq_file->private is always NULL and we always read the
spurious data of irq 0.
