[ Upstream commit 8a0efb8b101665a843205eab3d67ab09cb2d9a8d ]
Commit 3885c2b463f6 ("MIPS: CM: Add support for reporting CM cache
errors") adds cm2_causes[] array with map of error type ID and
pointers to the short description string. There is a mistake in
the table, since according to MIPS32 manual CM2_ERROR_TYPE = {17,18}
correspond to INTVN_WR_ERR and INTVN_RD_ERR, while the table
claims they have {0x17,0x18} codes. This is obviously hex-dec
copy-paste bug. Moreover codes {0x18 - 0x1a} indicate L2 ECC errors.
Fixes: 3885c2b463f6 ("MIPS: CM: Add support for reporting CM cache errors")
