From: Colin Ian King <colin.king@xxxxxxxxxxxxx> Currently the expression (nand_ctrl | BAM_MODE_EN) is always true no matter the value of nand_ctrl because the incorrect masking operator is being used. Fix this by using bit-wise & instead of |. Addresses-Coverity: ("Wrong operator used") Fixes: dd0c1fc8de12 ("mtd: rawnand: qcom: set BAM mode only if not set already") Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx> --- drivers/mtd/nand/raw/qcom_nandc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/mtd/nand/raw/qcom_nandc.c b/drivers/mtd/nand/raw/qcom_nandc.c index a3ef4288be27..37d95532ba7e 100644 --- a/drivers/mtd/nand/raw/qcom_nandc.c +++ b/drivers/mtd/nand/raw/qcom_nandc.c @@ -2790,7 +2790,7 @@ static int qcom_nandc_setup(struct qcom_nand_controller *nandc) * only if it is not in BAM mode.
