Subject: cxl: downgrade a warning message to debug level in cxl_probe_component_regs()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9474d586819940f00a98dd98015fe456f9b35452;p=linux.git

cxl: downgrade a warning message to debug level in cxl_probe_component_regs()

In cxl_probe_component_regs() the error message "Couldn't locate the
CXL.cache and CXL.mem capability array header." is potentially a false
positive error condition.

Downgrade the message from error level to debug level by using dev_dbg()
to print the message, and the end users won't worry about the message
anymore.
