Subject: lis3lv02d: Omit IRQF_ONESHOT if no threaded handler is provided
X-Git-Tag: v7.0-rc7~8^2~19
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f40b1401b6ad0f4dadfca4e7a69744352a2e4f8f;p=thirdparty%2Fkernel%2Fstable.git

lis3lv02d: Omit IRQF_ONESHOT if no threaded handler is provided

The lis3lv02d started triggering a WARN in the IRQ code because it
passes IRQF_ONESHOT to request_threaded_irq() even when thread_fn is
NULL, which is an invalid combination.

So set the flag only if thread_fn is non-NULL.
