You should check for returned errors for these functions.
Ok.
Will this be better?
static void lcd_hv070wsa_set_power(struct plat_lcd_data *pd, \
No need ''
unsigned int power)
{ int ret; unsigned long flag = power ? GPIOF_OUT_INIT_HIGH : \
Same as above.
GPIOF_OUT_INIT_LOW;
ret = gpio_request_one(EXYNOS4_GPE3(4), flag, "GPE3_4");
if (ret) printk(KERN_ERR "Could not request gpio for LCD power"); }
How about following?
if (power) ret = gpio_request_one(EXYNOS4_GPE3(4), GPIOF_OUT_INIT_HIGH, "GPE3_4"); else ret = gpio_request_one(EXYNOS4_GPE3(4), GPIOF_OUT_INIT_LOW, "GPE3_4");
if (ret) pr_err("failed to request gpio for LCD power: %d\n", ret);
Thanks.
