Messages in this thread Patch in this message |  | | From | Rasmus Villemoes <> | Subject | [PATCH v2 7/8] powerpc/pseries: use seq_open_data in hcall_inst_seq_open | Date | Sat, 18 Aug 2018 15:24:33 +0200 |
| |
This code should check the return value of seq_open(); if it failed, file->private_data is NULL. But we can avoid the issue entirely and simplify the code by letting seq_open_data() set the ->private member.
Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> --- Depends on 1/8 introducing seq_open_data.
