Subject: modbus: Ignore unknown/unsupported types.
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=7714a23058fcf1fbffa1208fb02f854947f0617f

modbus: Ignore unknown/unsupported types.

Without this, e.g. the recently added 'IDLE' ptype of the UART decoder
would cause issues.
