Nathan Chancellor 21b34a3a20 memstick: core: Zero initialize id_reg in h_memstick_read_dev_id() ... A new warning in clang [1] points out that id_reg is uninitialized then passed to memstick_init_req() as a const pointer: drivers/memstick/core/memstick.c:330:59: error: variable 'id_reg' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 330 | memstick_init_req(&card->current_mrq, MS_TPC_READ_REG, &id_reg, | ^~~~~~ Commit de182cc8e8 ("drivers/memstick/core/memstick.c: avoid -Wnonnull warning") intentionally passed this variable uninitialized to avoid an -Wnonnull warning from a NULL value that was previously there because id_reg is never read from the call to memstick_init_req() in h_memstick_read_dev_id(). Just zero initialize id_reg to avoid the warning, which is likely happening in the majority of builds using modern compilers that support '-ftrivial-auto-var-init=zero'.
