[PATCH rdma-next v2 2/2] RDMA: Use dma_map_sgtable for map umem pages

From: Maor Gottlieb In order to avoid incorrect usage of sg_table fields, change umem to use dma_map_sgtable for map the pages for DMA. Since dma_map_sgtable update the nents field (number of DMA entries), there is no need anymore for nmap variable, hence do some cleanups accordingly. Signed-off

[PATCH rdma-next v2 1/2] lib/scatterlist: Fix wrong update of orig_nents

From: Maor Gottlieb orig_nents should represent the number of entries with pages, but __sg_alloc_table_from_pages sets orig_nents as the number of total entries in the table. This is wrong when the API is used for dynamic allocation where not all the table entries are mapped with pages. It wasn't

[PATCH] staging/fbtft: Remove all strcpy() uses

strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. The safe replacement is strscpy() but in this case it is simpler to add NULL to the first position since we want to empty the str

[PATCH] backlight: pwm_bl: Avoid backlight flicker if backlight control GPIO is input

If the backlight enable GPIO is configured as input, the driver currently unconditionally forces the GPIO to output-enable. This can cause backlight flicker on boot e.g. in case the GPIO should not be enabled before the PWM is configured and is correctly pulled low by external resistor. Fix this b

[PATCH] fbdev: simplefb: limit its use to DRM_SIMPLEDRM=n

When DRM_SIMPLEDRM=m, all of FB_CFB_{FILLRECT,COPYAREA,IMAGEBLIT} are =m, causing undefined references in fbdev/simplefb.o. By restricting FB_SIMPLEFB to be set only when DRM_SIMPLEDRM is not set, the FB_CFB_* symbols are =y and the build completes without these undefined references. IOW, really
