Message-ID: <20190704055645.GA15471@kroah.com> MIME-Version: 1.0 Content-Disposition: inline User-Agent: Mutt/1.12.1 (2019-06-15) Sender: linux-fpga-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-fpga@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP This is a driver, do not call "raw" sysfs functions, instead call driver core ones. Specifically convert the use of sysfs_create_files() and sysfs_remove_files() to use device_add_groups() and device_remove_groups() Cc: Wu Hao Cc: Alan Tull Cc: Moritz Fischer Cc: linux-fpga@vger.kernel.org Signed-off-by: Greg Kroah-Hartman --- drivers/fpga/dfl-afu-main.c | 14 ++++++++------ drivers/fpga/dfl-fme-main.c | 7 ++++--- 2 files changed, 12 insertions(+), 9 deletions(-) diff --git a/drivers/fpga/dfl-afu-main.c b/drivers/fpga/dfl-afu-main.c index 02baa6a227c0..68b4d0874b93 100644 --- a/drivers/fpga/dfl-afu-main.c +++ b/drivers/fpga/dfl-afu-main.c @@ -141,10 +141,11 @@ id_show(struct device *dev, struct device_attribute *attr, char *buf) } static DEVICE_ATTR_RO(id); -static const struct attribute *port_hdr_attrs[] = { +static struct attribute *port_hdr_attrs[] = { &dev_attr_id.attr, NULL, }; +ATTRIBUTE_GROUPS(port_hdr); static int port_hdr_init(struct platform_device *pdev, struct dfl_feature *feature) @@ -153,7 +154,7 @@ static int port_hdr_init(struct platform_device *pdev, port_reset(pdev); - return sysfs_create_files(&pdev->dev.kobj, port_hdr_attrs); + return device_add_groups(&pdev->dev, port_hdr_groups); } static void port_hdr_uinit(struct platform_device *pdev, @@ -161,7 +162,7 @@ static void port_hdr_uinit(struct platform_device *pdev, { dev_dbg(&pdev->dev, "PORT HDR UInit.\n"); - sysfs_remove_files(&pdev->dev.kobj, port_hdr_attrs); + device_remove_groups(&pdev->dev, port_hdr_groups); } static long @@ -214,10 +215,11 @@ afu_id_show(struct device *dev, struct device_attribute *attr, char *buf) } static DEVICE_ATTR_RO(afu_id); -static const struct attribute *port_afu_attrs[] = { +static struct attribute *port_afu_attrs[] = { &dev_attr_afu_id.attr, NULL }; +ATTRIBUTE_GROUPS(port_afu); static int port_afu_init(struct platform_device *pdev, struct dfl_feature *feature) @@ -234,7 +236,7 @@ static int port_afu_init(struct platform_device *pdev, if (ret) return ret; - return sysfs_create_files(&pdev->dev.kobj, port_afu_attrs); + return device_add_groups(&pdev->dev, port_afu_groups); } static void port_afu_uinit(struct platform_device *pdev, @@ -242,7 +244,7 @@ static void port_afu_uinit(struct platform_device *pdev, { dev_dbg(&pdev->dev, "PORT AFU UInit.\n"); - sysfs_remove_files(&pdev->dev.kobj, port_afu_attrs); + device_remove_groups(&pdev->dev, port_afu_groups); } static const struct dfl_feature_ops port_afu_ops = { diff --git a/drivers/fpga/dfl-fme-main.c b/drivers/fpga/dfl-fme-main.c index 086ad2420ade..0be4635583d5 100644 --- a/drivers/fpga/dfl-fme-main.c +++ b/drivers/fpga/dfl-fme-main.c @@ -72,12 +72,13 @@ static ssize_t bitstream_metadata_show(struct device *dev, } static DEVICE_ATTR_RO(bitstream_metadata); -static const struct attribute *fme_hdr_attrs[] = { +static struct attribute *fme_hdr_attrs[] = { &dev_attr_ports_num.attr, &dev_attr_bitstream_id.attr, &dev_attr_bitstream_metadata.attr, NULL, }; +ATTRIBUTE_GROUPS(fme_hdr); static int fme_hdr_init(struct platform_device *pdev, struct dfl_feature *feature) @@ -89,7 +90,7 @@ static int fme_hdr_init(struct platform_device *pdev, dev_dbg(&pdev->dev, "FME cap %llx.\n", (unsigned long long)readq(base + FME_HDR_CAP)); - ret = sysfs_create_files(&pdev->dev.kobj, fme_hdr_attrs); + ret = device_add_groups(&pdev->dev, fme_hdr_groups); if (ret) return ret; @@ -100,7 +101,7 @@ static void fme_hdr_uinit(struct platform_device *pdev, struct dfl_feature *feature) { dev_dbg(&pdev->dev, "FME HDR UInit.\n"); - sysfs_remove_files(&pdev->dev.kobj, fme_hdr_attrs); + device_remove_groups(&pdev->dev, fme_hdr_groups); } static const struct dfl_feature_ops fme_hdr_ops = {
