scripts/gdb: fix list_for_each

2021-02-26T17:41:05+00:00

If the list is uninitialized (next pointer is NULL), list_for_each gets stuck in an infinite loop. Print a message and treat list as empty.

scripts/gdb: clean up error handling in list helpers

2019-05-15T02:52:52+00:00

An incorrect argument to list_for_each is an internal error in gdb scripts so a TypeError should be raised. The gdb.GdbError exception type is intended for user errors such as incorrect invocation. Drop the type assertion in list_for_each_entry because list_for_each isn't going to suddenly yield something else. Applies to both list and hlist Link: http://lkml.kernel.org/r/c1d3fd4db13d999a3ba57f5bbc1924862d824f61.1556881728.git.leonard.crestez@nxp.com Signed-off-by: Leonard Crestez Reviewed-by: Stephen Boyd Cc: Jan Kiszka Cc: Jason Wessel Cc: Kieran Bingham Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
