[PATCH][next] tpm: remove redundant variable len

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Variable len is being accumulated but the value is never read. It is
redundant and can be removed. Cleans up clang scan build warning:

drivers/char/tpm/eventlog/tpm1.c:276:2: warning: Value stored to 'len' is never read [deadcode.DeadStores]
