[PATCH] staging: most: don't access hdm_ch before checking it valid

In try_start_dim_transfer(), pointer hdm_ch is accessed before checking. This may lead to a potential null pointer dereference. Fix this by dereferencing hdm_ch after calling BUG_ON(). Signed-off-by: Jing Xiangfeng --- drivers/staging/most/dim2/dim2.c | 3 ++- 1 file changed, 2 insertions(+), 1

[PATCH] staging: olpc_dcon: Do not call platform_device_unregister() in dcon_probe()

In dcon_probe(), when platform_device_add() failes to add the device, it jumps to call platform_device_unregister() to remove the device, which is unnecessary. So use platform_device_put() instead. Fixes: 53c43c5ca133 ("Revert "Staging: olpc_dcon: Remove obsolete driver"")
