From a07bf39a65cb5eb4e38426afc7d5e00d560211da Mon Sep 17 00:00:00 2001 From: Lidza Louina Date: Fri, 4 Oct 2013 12:18:30 -0400 Subject: [PATCH] staging: dgnc: changes arguments in sizeof The arguments that were passed into sizeof were generic. This patch changes this by putting the actual item that we need a size of instead. For example: - kzalloc(sizeof(struct dgnc_board), GFP_KERNEL); + kzalloc(sizeof(*brd), GFP_KERNEL); Signed-off-by: Lidza Louina Signed-off-by: Greg Kroah-Hartman --- drivers/staging/dgnc/dgnc_driver.c | 4 ++-- drivers/staging/dgnc/dgnc_mgmt.c | 2 +- drivers/staging/dgnc/dgnc_tty.c | 24 ++++++++++++------------ 3 files changed, 15 insertions(+), 15 deletions(-) diff --git a/drivers/staging/dgnc/dgnc_driver.c b/drivers/staging/dgnc/dgnc_driver.c index c398193e9b85..4271fa38a46c 100644 --- a/drivers/staging/dgnc/dgnc_driver.c +++ b/drivers/staging/dgnc/dgnc_driver.c @@ -487,7 +487,7 @@ static int dgnc_found_board(struct pci_dev *pdev, int id) /* get the board structure and prep it */ brd = dgnc_Board[dgnc_NumBoards] = - kzalloc(sizeof(struct dgnc_board), GFP_KERNEL); + kzalloc(sizeof(*brd), GFP_KERNEL); if (!brd) { APR(("memory allocation for board structure failed\n")); return -ENOMEM; @@ -495,7 +495,7 @@ static int dgnc_found_board(struct pci_dev *pdev, int id) /* make a temporary message buffer for the boot messages */ brd->msgbuf = brd->msgbuf_head = - kzalloc(sizeof(char) * 8192, GFP_KERNEL); + kzalloc(sizeof(u8) * 8192, GFP_KERNEL); if (!brd->msgbuf) { kfree(brd); APR(("memory allocation for board msgbuf failed\n")); diff --git a/drivers/staging/dgnc/dgnc_mgmt.c b/drivers/staging/dgnc/dgnc_mgmt.c index bb39f5dfa043..354458c5068e 100644 --- a/drivers/staging/dgnc/dgnc_mgmt.c +++ b/drivers/staging/dgnc/dgnc_mgmt.c @@ -209,7 +209,7 @@ long dgnc_mgmt_ioctl(struct file *file, unsigned int cmd, unsigned long arg) uint board = 0; uint channel = 0; - if (copy_from_user(&ni, uarg, sizeof(struct ni_info))) { + if (copy_from_user(&ni, uarg, sizeof(ni))) { return -EFAULT; } diff --git a/drivers/staging/dgnc/dgnc_tty.c b/drivers/staging/dgnc/dgnc_tty.c index 1350d6266524..c6fee11632f7 100644 --- a/drivers/staging/dgnc/dgnc_tty.c +++ b/drivers/staging/dgnc/dgnc_tty.c @@ -200,8 +200,8 @@ int dgnc_tty_register(struct dgnc_board *brd) DPR_INIT(("tty_register start\n")); - memset(&brd->SerialDriver, 0, sizeof(struct tty_driver)); - memset(&brd->PrintDriver, 0, sizeof(struct tty_driver)); + memset(&brd->SerialDriver, 0, sizeof(brd->SerialDriver)); + memset(&brd->PrintDriver, 0, sizeof(brd->PrintDriver)); brd->SerialDriver.magic = TTY_DRIVER_MAGIC; @@ -222,12 +222,12 @@ int dgnc_tty_register(struct dgnc_board *brd) * The kernel wants space to store pointers to * tty_struct's and termios's. */ - brd->SerialDriver.ttys = kzalloc(brd->maxports * sizeof(struct tty_struct *), GFP_KERNEL); + brd->SerialDriver.ttys = kzalloc(brd->maxports * sizeof(*brd->SerialDriver.ttys), GFP_KERNEL); if (!brd->SerialDriver.ttys) return -ENOMEM; kref_init(&brd->SerialDriver.kref); - brd->SerialDriver.termios = kzalloc(brd->maxports * sizeof(struct ktermios *), GFP_KERNEL); + brd->SerialDriver.termios = kzalloc(brd->maxports * sizeof(*brd->SerialDriver.termios), GFP_KERNEL); if (!brd->SerialDriver.termios) return -ENOMEM; @@ -271,11 +271,11 @@ int dgnc_tty_register(struct dgnc_board *brd) * tty_struct's and termios's.
