Subject: i2s: Fix unportable use of struct.pack
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=30c855f60df2ae5d2edc568c51920f215ab38e0c;p=libsigrokdecode.git

i2s: Fix unportable use of struct.pack

Using the format string 'I' with the default (implied) prefix '@'
results in both word size and endianness being platform dependent.
In this case standard size (32 bits) and little endianness is
required, so the prefix '<' needs to be used.
