Subject: bpf: Simplify character output in seq_print_delegate_opts()
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=f157f9cb85b49745754f8c301c59c6ca110e865f;p=linux-2.6-block.git

bpf: Simplify character output in seq_print_delegate_opts()

Single characters should be put into a sequence.
Thus use the corresponding function “seq_putc” for two selected calls.

This issue was transformed by using the Coccinelle software.
