add_mtd_blktrans_dev() imposes a maximum of 257 devices per block translator. This was presumably meant to prevent overflow back in the days of 8-bit minor numbers. Instead, check against MINORMASK and the limits of the partition naming scheme. Signed-off-by:

Since we allocate struct mtd_blktrans_dev for each block device, we can add our own structure members to the end. Therefore embed struct mtd_blktrans_dev in struct mtdblk_dev and remove the static array of struct mtdblk_dev. Also remove the redundant pointer to struct mtd_info. This is preparation for removing the static limit on the number of MTD devices. Signed-off-by:

In mtd_ioctl MEMGETREGIONINFO the region_user_info pointer ur is cast in __kernel space. This produces a number of sparse warnings like: warning: cast removes address space of expression warning: incorrect type in initializer (different address spaces) expected unsigned int const [noderef] <asn:1>*register __p got unsigned int *<noident> Since argp is already a void __user * just use it dirrectly without the cast and make ur a __user *.

In the inline function cfi_build_cmd_addr, the cast of cmd_ofs to an uint8_t produces a sparse warning of the type: warning: cast truncates bits from constant value (2aa becomes aa) Quiet the warning by masking cmd_ofs with 0xff and remove the cast. Signed-off-by:

The clock must already be off after mtd->suspend. Disabling it again results in an negative overflow of the clock usage count. This didn't hurt as mxcnd_resume undid it after wake up. Signed-off-by:

The probe function calls platform_set_drvdata with a valid pointer when the probe is successful. As mxcnd_suspend and mxcnd_resume are only called on bound devices, platform_get_drvdata always returns non-NULL. This fix isn't critical as the pointer is always valid so it doesn't matter if the compiler generated code for it or not. Signed-off-by:

Commit e9903060 ("mtd: orion_nand.c: add error handling and use resource_size()") introduced a build error -- it assigns something to a undeclared variable 'err', whereas the rest of the code uses 'ret' for this task. This patch fixes this typo and thus removes the build failure. Signed-off-by:

crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic. Signed-off-by:
