    Subject[PATCH AUTOSEL 5.14 05/26] device property: build kunit tests without structleak plugin
    Date
    From: Brendan Higgins <brendanhiggins@google.com>

    [ Upstream commit 6a1e2d93d55b000962b82b9a080006446150b022 ]

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

    ../drivers/base/test/property-entry-test.c:492:1: warning: the frame size of 2832 bytes is larger than 2048 bytes [-Wframe-larger-than=]
    ../drivers/base/test/property-entry-test.c:322:1: warning: the frame size of 2080 bytes is larger than 2048 bytes [-Wframe-larger-than=]
    ../drivers/base/test/property-entry-test.c:250:1: warning: the frame size of 4976 bytes is larger than 2048 bytes [-Wframe-larger-than=]
    ../drivers/base/test/property-entry-test.c:115:1: warning: the frame size of 3280 bytes is larger than 2048 bytes [-Wframe-larger-than=]

    Turn it off in this file.
