From c3cba9281ba39f3aef377fe52890e2d8f1e6dae3 Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Thu, 12 Apr 2012 12:49:14 -0700 Subject: [PATCH] drivers/rtc/rtc-s3c.c: add placeholder for driver private data Driver data field is a pointer, hence assigning that to an integer results in compilation warnings. Fixes following compilation warnings: drivers/rtc/rtc-s3c.c: In function `s3c_rtc_get_driver_data': drivers/rtc/rtc-s3c.c:452:3: warning: return makes integer from pointer without a cast [enabled by default] drivers/rtc/rtc-s3c.c: At top level: drivers/rtc/rtc-s3c.c:674:3: warning: initialization makes pointer from integer without a cast [enabled by default] drivers/rtc/rtc-s3c.c:674:3: warning: (near initialization for `s3c_rtc_dt_match[1].data') [enabled by default] drivers/rtc/rtc-s3c.c:677:3: warning: initialization makes pointer from integer without a cast [enabled by default] drivers/rtc/rtc-s3c.c:677:3: warning: (near initialization for `s3c_rtc_dt_match[2].data') [enabled by default] drivers/rtc/rtc-s3c.c:680:3: warning: initialization makes pointer from integer without a cast [enabled by default] drivers/rtc/rtc-s3c.c:680:3: warning: (near initialization for `s3c_rtc_dt_match[3].data') [enabled by default] Signed-off-by: Tushar Behera Cc: Heiko Stuebner Cc: Alessandro Zummo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/rtc/rtc-s3c.c | 23 ++++++++++++++++++----- 1 file changed, 18 insertions(+), 5 deletions(-) diff --git a/drivers/rtc/rtc-s3c.c b/drivers/rtc/rtc-s3c.c index 2087953f108d..3f3a29752369 100644 --- a/drivers/rtc/rtc-s3c.c +++ b/drivers/rtc/rtc-s3c.c @@ -40,6 +40,10 @@ enum s3c_cpu_type { TYPE_S3C64XX, }; +struct s3c_rtc_drv_data { + int cpu_type; +}; + /* I have yet to find an S3C implementation with more than one * of these rtc blocks in */ @@ -446,10 +450,12 @@ static const struct of_device_id s3c_rtc_dt_match[]; static inline int s3c_rtc_get_driver_data(struct platform_device *pdev) { #ifdef CONFIG_OF + struct s3c_rtc_drv_data *data; if (pdev->dev.of_node) { const struct of_device_id *match; match = of_match_node(s3c_rtc_dt_match, pdev->dev.of_node); - return match->data; + data = (struct s3c_rtc_drv_data *) match->data; + return data->cpu_type; } #endif return platform_get_device_id(pdev)->driver_data; @@ -664,20 +670,27 @@ static int s3c_rtc_resume(struct platform_device *pdev) #define s3c_rtc_resume NULL #endif +static struct s3c_rtc_drv_data s3c_rtc_drv_data_array[] = { + [TYPE_S3C2410] = { TYPE_S3C2410 }, + [TYPE_S3C2416] = { TYPE_S3C2416 }, + [TYPE_S3C2443] = { TYPE_S3C2443 }, + [TYPE_S3C64XX] = { TYPE_S3C64XX }, +}; + #ifdef CONFIG_OF static const struct of_device_id s3c_rtc_dt_match[] = { { .compatible = "samsung,s3c2410-rtc", - .data = TYPE_S3C2410, + .data = &s3c_rtc_drv_data_array[TYPE_S3C2410], }, { .compatible = "samsung,s3c2416-rtc", - .data = TYPE_S3C2416, + .data = &s3c_rtc_drv_data_array[TYPE_S3C2416], }, { .compatible = "samsung,s3c2443-rtc", - .data = TYPE_S3C2443, + .data = &s3c_rtc_drv_data_array[TYPE_S3C2443], }, { .compatible = "samsung,s3c6410-rtc", - .data = TYPE_S3C64XX, + .data = &s3c_rtc_drv_data_array[TYPE_S3C64XX], }, {}, };
