[PATCH -next] RDMA/bnxt_re: Remove set but not used variable 'pg_size'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fixes gcc '-Wunused-but-set-variable' warning:

drivers/infiniband/hw/bnxt_re/qplib_res.c: In function '__alloc_pbl':
drivers/infiniband/hw/bnxt_re/qplib_res.c:109:13: warning:
 variable 'pg_size' set but not used [-Wunused-but-set-variable]

commit 0c4dcd602817 ("RDMA/bnxt_re: Refactor hardware queue memory allocation")
involved this, but not used, so remove it.
