[PATCH 3/3] staging: dgnc: clean up the dgnc_get_modem_info()

the "ch" in dgnc_get_modem_info() was already checked before calling this function and also if "ch" is not NULL, dgnc_get_mstat() returns valid value so it doesn't need to check an error. Signed-off-by: Daeseok Youn --- drivers/staging/dgnc/dgnc_tty.c | 12 +--- 1 file changed, 1 inserti

[PATCH] staging: dgnc: Fix a NULL pointer dereference
