w1: ds2438: remove redundant initialization of variable crc
Variable crc is being initialized with a value that is never read, it is being re-assigned later on. The initialization is redundant and can be removed. Cleans up clang scan build warning: warning: Value stored to 'crc' is never read [deadcode.DeadStores] Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Link: https://lore.kernel.org/r/20220522194622.13277-1-colin.i.king@gmail.com Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
