Stephan Gerhold d81ee62948 net: wwan: mhi_wwan_mbim: Silence sequence number glitch errors ... [ Upstream commit 0d1fac6d26 ] When using the Qualcomm X55 modem on the ThinkPad X13s, the kernel log is constantly being filled with errors related to a "sequence number glitch", e.g.: [ 1903.284538] sequence number glitch prev=16 curr=0 [ 1913.812205] sequence number glitch prev=50 curr=0 [ 1923.698219] sequence number glitch prev=142 curr=0 [ 2029.248276] sequence number glitch prev=1555 curr=0 [ 2046.333059] sequence number glitch prev=70 curr=0 [ 2076.520067] sequence number glitch prev=272 curr=0 [ 2158.704202] sequence number glitch prev=2655 curr=0 [ 2218.530776] sequence number glitch prev=2349 curr=0 [ 2225.579092] sequence number glitch prev=6 curr=0 Internet connectivity is working fine, so this error seems harmless. It looks like modem does not preserve the sequence number when entering low power state; the amount of errors depends on how actively the modem is being used. A similar issue has also been seen on USB-based MBIM modems [1]. However, in cdc_ncm.c the "sequence number glitch" message is a debug message instead of an error. Apply the same to the mhi_wwan_mbim.c driver to silence these errors when using the modem.
