Subject: usb_power_delivery: fixup a Python style nit (dict lookup fallback)
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=279331bd318c853e3aaac746167eb81179771750;hp=57ba804a912c0753aefcaf8eee2f19ad7f5e86e5

usb_power_delivery: fixup a Python style nit (dict lookup fallback)

Use the dictionary's .get() method in combination with a default result
parameter, instead of an explicit "k in dictvar" test and a conditional
assignment.
