Subject: [2.6 patch] drivers/infiniband/hw/cxgb3/: possible cleanups
This patch contains the following possible cleanups:
- don't mark static functions in C files as inline - gcc should know
best whether inlining makes sense
- never compile the unused cxio_dbg.c
- make the following needlessly global functions static:
- cxio_hal.c: cxio_hal_clear_qp_ctx()
- iwch_provider.c: iwch_get_qp()
- #if 0 the following unused global functions:
- cxio_hal.c: cxio_allocate_stag()
- cxio_resource.: cxio_hal_get_rhdl()
- cxio_resource.: cxio_hal_put_rhdl()
Signed-off-by: Adrian Bunk <bunk@...sta.de>
