mtd: docg3: use devm_platform_ioremap_resource()

2026-09-09T07:55:35+00:00

Replace the open-coded platform_get_resource(IORESOURCE_MEM, 0) plus devm_ioremap() sequence with devm_platform_ioremap_resource(), which folds the resource lookup, region reservation and mapping into one step and returns an ERR_PTR checked with IS_ERR()/PTR_ERR(). The canonical docg3 register window is DOC_IOSPACE_SIZE (0x2000), which is the size any platform provides for this device, so mapping the full resource is equivalent to the previous fixed-size devm_ioremap(). Built for ARM (multi_v7_defconfig + CONFIG_MTD_DOCG3) with LLVM=1; drivers/mtd/devices/docg3.o compiles cleanly.

mtd: mtd_intel_dg: reset poll counter for each erase

2026-09-04T18:32:21+00:00

The non-posted erase polling counter is initialized only once per MTD erase request. Large requests therefore share the polling budget across all 4K erase commands and can fail with -ETIME even though no individual command timed out. Reset the counter for each 4K erase command so every operation gets the intended completion timeout.

mtd: block2mtd: Fix divide error when erase_size is zero

2026-09-04T17:01:53+00:00

The erase size is parsed from the "block2mtd" module parameter and can be set to zero. add_device() then evaluates if (size % erase_size) with a zero divisor, which triggers a divide error: divide error: 0000 [#1] PREEMPT SMP PTI RIP: 0010:add_device drivers/mtd/devices/block2mtd.c:296 [inline] RIP: 0010:block2mtd_setup2+0x592/0xda0 drivers/mtd/devices/block2mtd.c:459 Call Trace: block2mtd_setup+0x27/0xe0 drivers/mtd/devices/block2mtd.c:476 param_attr_store+0x214/0x310 kernel/params.c:589 module_attr_store+0x65/0x90 kernel/params.c:904 kernfs_fop_write_iter+0x3a4/0x540 fs/kernfs/file.c:345 ... Reject a zero erase size before performing the modulo operation so the existing "erasesize must be a divisor of device size" error path reports the invalid argument and frees the device.

mtd: intel-dg: Fix runtime PM error path in probe

2026-07-17T15:49:13+00:00

intel_dg_mtd_probe() allocates region names before enabling runtime PM and before calling pm_runtime_resume_and_get(). If kasprintf() fails while building a region name, the error path jumps to err, which calls pm_runtime_put(). At that point there has not been a successful pm_runtime_resume_and_get() call to balance, so the runtime PM usage count can underflow. Jump to err_norpm from the kasprintf() failure path, as the runtime PM reference has not been acquired yet.

mtd: mchp23k256: use SPI match data for chip caps

2026-07-03T13:46:01+00:00

The driver stores chip capacity information in both the OF match table and the SPI id table. Probe currently uses of_device_get_match_data(), so a non-OF SPI modalias match falls back to mchp23k256_caps even when the SPI id table selected a different part. Use spi_get_device_match_data() so SPI id-table driver_data is consumed when OF match data is absent. This keeps the existing default fallback while avoiding the wrong MTD geometry for id-table-only matches.
