Subject: EDAC/mc: Carve out error increment into a separate function
Git-commit: 6334dc4e3ff53031a2d522b826c4fab92cfdea93
Patch-mainline: v5.7-rc1
References: jsc#SLE-9482
Carve out the error_count increment into a separate function
edac_inc_csrow(). This better separates code and reduces the indentation
level.
Implementation note: The function edac_inc_csrow() counts the same
as before, ->ce_count is only incremented if row >= 0. This is esp.
true for the case of (!e->enable_per_layer_report). Here, a DIMM was
not found, variable row still has a value of -1 and ->ce_count is not
incremented.
