Subject: crypto: caam - remove unreachable code in report_ccb_status()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9305dff7ab8b5e1aef2c4c5c733ce7e1dc345433;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

crypto: caam - remove unreachable code in report_ccb_status()

ERRID is a 4-bit field.
Since err_id values are in [0..15] and err_id_list array size is 16,
the condition "err_id < ARRAY_SIZE(err_id_list)" is always true.
