Subject: ocfs2/dlm: clean up useless BUG_ON default case in dlm_finalize_reco_handler()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=46832b2de5fa42519c4924a9d0751d9297012ca9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ocfs2/dlm: clean up useless BUG_ON default case in dlm_finalize_reco_handler()

The value of 'stage' must be between 1 and 2, so the switch can't reach
the default case.
