Subject: input: decorate sr_input_find() parameter as const
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=e3847923a4ddf50349dcf21259cd4a02722c2960;p=libsigrok.git

input: decorate sr_input_find() parameter as const

The caller's input module name is only read for comparison. Decorate it
with the 'const' attribute to simplify calling application code.
