Subject: [PATCH 5.14 128/169] iio/test-format: build kunit tests without structleak plugin

From: Brendan Higgins <brendanhiggins@...gle.com>

[ Upstream commit 2326f3cdba1d105b68cc1295e78f17ae8faa5a76 ]

The structleak plugin causes the stack frame size to grow immensely when
used with KUnit:

../drivers/iio/test/iio-test-format.c: In function ‘iio_test_iio_format_value_fixedpoint’:
../drivers/iio/test/iio-test-format.c:98:1: warning: the frame size of 2336 bytes is larger than 2048 bytes [-Wframe-larger-than=]

Turn it off in this file.
