Subject: sunrpc: fix braino in ->poll()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1711fd9addf214823b993468567cab1f8254fc51;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

sunrpc: fix braino in ->poll()

POLL_OUT isn't what callers of ->poll() are expecting to see; it's
actually __SI_POLL | 2 and it's a siginfo code, not a poll bitmap
bit...
